C Correct answer
Explanation

Sorghum is a genus of plants in the grass family. Most species are native to Australia, with some extending to Africa, Asia, Mesoamerica and certain islands in the Indian and Pacific Oceans. One species is grown for grain and many of which are used as fodder plants, either cultivated or as part of pasture. The plants are cultivated in warm climates worldwide and naturalized in many places.
Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae. Sorghum vulgare is the botanical name of jawar. Oryza sativa, commonly known as Asian rice, is the plant species most commonly referred to in English as rice. 

Oryza sativa is a grass with a genome consisting of 430Mb across 12 chromosomes.
Triticum aestivum (wheat) and Pennisetum typhoides (pearl millet) are not the botanical names of Jawar and Rice. 
Therefore, the correct answer is option C.

B Correct answer
Explanation

Coir is a natural fibre extracted from the husk of coconut and used in products such as floor mats, doormats, brushes, mattresses, etc. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut.  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). An untouched coconut has three layers. The outermost layer, which is typically smooth with a greenish color, is called as the exocarp. The next layer is the fibrous husk or mesocarp, which ultimately surrounds the hard woody layer called as the endocarp. The endocarp surrounds the seed. Coir of commerce is obtained from mesocarp of coconut. 
Therefore, the correct answer is option B.
