When the septa between the locules of the capsule split and the fruit opens to release the seeds, then this type of dehiscence is called as septicidal dehiscence. For example, Datura. The fruit of Datura is septicidal capsule but its dehiscence is of septifragal nature in which placenta remains attached in the centre of undivided fruit and pericarp's segment becomes separated.

Fruit of groundnut is a lomentum. Lomentum is a simple, dry, schizocarpic fruit. The fruit is constricted or partitioned between seeds into a number of one-seeded compartments. The fruit breaks into one seeded indehiscent segments. 

Pepo (berries) is a type of fleshy fruit. They are simple fruit created from a single ovary. In pepo, the berry skin is leathery as in Cucurbitaceae family.

Therefore, the correct answer is option A.

Caryopsis is a type of simple dry fruit that has one seed or monocarpellate (formed from a single carpel) and indehiscent (not opening at maturity). In a caryopsis, the pericarp is fused with the thin seed coat and the fruit wall and the seed are intimately fused into a single unit example Maize
So, the correct answer is 'one seeded fruit'

Oil glands are present in many plants. They are made of small groups of thin walled cells which are full of cytoplasmic contents. These cells possess secretory activities. Such, secretions are collected in cavities which are developed either schizogenously or lysigenously. Schizogenous cavity is formed by separation of cells at middle lamellae. Lysigenous cavity is made by dissolution of cells. Schizogenous oil glands are present in leaves and bark of Eucalyptus plant. Lysigenous oil glands are present pericarp of fruits of Citrus.
Thus, the correct answer is option C.
