Legume or pod fruits are monocarpellary (from monomerous gynoecium), generally multiseeded, hypogynous flower, marginal placentation. Dehiscence is on two sides (ventral and dorsal) from the apex of the fruit. Characteristic for Fabaceae. Monocarpillary means ovary with one carpel. The legume fruits do not develops from inferior ovary, bicarpillary ovary and multicarpillary ovary. 
Thus, the correct answer is option B.

In agriculture, the majority of the biomass produced comes from monocots. These include not only major grains (rice, wheat, maize, etc.), but also forage grasses, sugar cane, and the bamboos. Other economically important monocot crops include various palms (Arecaceae), bananas (Musaceae), gingers and their relatives, turmeric and cardamom (Zingiberaceae) and the onions and garlic family (Amaryllidaceae). Additionally, most of the horticultural bulbs, plants cultivated for their blooms, are monocots, such as lilies, daffodils, irises, amaryllis, cannas, bluebells and tulips. Maize is a flowering plant and not a dicot or pteridophyte. Almond is a dicot as it has  two cotyledons in their seeds. 

Coconuts are classified as a fibrous one-seeded drupe. A drupe is a fruit with a hard stony covering enclosing the seed (like a peach or olive) and comes from the word drupa meaning overripe olive. A coconut, and all drupes, have three layers, the exocarp (outer layer), the mesocarp (fleshy middle layer) and the endocarp (hard, woody layer that surrounds the seed).
Cypsela is an achene like fruit derived from the individual florets in a capitulum (e.g., Dandelion). Berry redcurrant, gooseberry, tomato, cranberry.
Cremocarp, is a dry fruit that is a type of schizocarp formed from two one-seeded carpels. The carpels remain separate and form indehiscent mericarps that are attached to a central supporting strand (carpophore) for some time before dispersal. It is characteristic of the Umbelliferae (Apiaceae, carrot family). 
Therefore, the correct answer is option A.

Radicle is the first part of a seedling to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant and grows downward in the soil.
Plumule is the young shoot of  a plant embryo above the cotyledons, consisiting of the epicotyl and often of immature leaves.
Cotyledon is the significant part of the embryo within the seed of a plant. Upon germination, the cotyledon may become the embryonic first leaves of a seedling.
Ovule is the structure that gives rise to and contains female reproductive cells.
Thus, the correct answer is option (B), 'Plumule'.

Caryopsis fruit is found in a wheat. A caryopsis is a type of simple dry fruit one that is monocarpellate, indehiscent and resembles an achene, except that in a caryopsis, the pericarp is fused with the thin seed coat. The caryopsis is popularly called as a grain and is the fruit typical of the family Poaceae.
Thus, the correct answer is option A.

Orchid seeds are small, light and contain little food reserves. A single seed capsule may contain1,500 to 3,000,000 seeds. Orchid seeds are small, dry, dusty and weighing as little as 0.004 mg.
So, the correct answer is 'small and light'

A berry fruit is fleshy and multiseeded. Berry is a fleshy fruit produced from a single flower and containing one ovary. Grapes and bananas are two common examples. The berry is the most common type of fleshy fruit in which the entire ovary wall ripens into an edible pericarp. They may have one or more carpels. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, that have air rather than pulp around their seeds.
Thus, the correct answer is option B.

The coconut tree is in the family of palm trees, and palm trees are monocotyledons. Almonds, mango and sunflower are dicots. 

Trichoblasts are specialized epidermal cells (root hairs) found at the periphery of the root, while other structures like fusiform cells or tyloses are located deeper within the plant axis.

Seeds germinate in the presence of warmth, moisture and air. No light is needed for germination. Seeds generally contain starch as food supply. So, light is not needed for food production also during germination.
