• White Revolution in India was a plan of three phases launched in 1970 by the National Dairy Development Board. 
• Its aim was to increase India's dairy production until India became self-sufficient in milk. 
• This program was highly successful and in 1998, India became the largest milk producer in the world. Thus the correct answer is option C.

Jamnapari and Black Bengal are the breeds of goats. The Jamnapari goats are of Indian origin and are reared for its high milk and meat yielding capacity. Black Bengal goats are usually reared in Bangladesh. They are reared for milk and meat and generates employment for the people. Thus, the correct answer is A.

The productivity of plants as biofuel or biomaterial crops is established by both the yield of plant biomass per unit area of land and the efficiency of conversion of the biomass to biofuel. Genomics approaches support genetic selection strategies to deliver significant genetic improvement of plants as sources of biomass for biofuel manufacture. Genetic modification of plants provides a further range of options for improving the composition of biomass and for plant modifications to assist the fabrication of biofuels. The relative carbohydrate and lignin content influences the deconstruction of plant cell walls to biofuels. Key options for facilitating the deconstruction leading to higher monomeric sugar release from plants include increasing cellulose content, reducing cellulose crystallinity, and/or altering the amount or composition of noncellulosic polysaccharides or lignin. Modification of chemical linkages within and between these biomass components may improve the ease of deconstruction. Expression of enzymes in the plant may provide a cost-effective option for biochemical conversion to biofuel.

Beewax is the natural secretion of the worker bees and is poured out in thin delicate flakes. It is made of:(i) even numbered alcohols. (ii) even numbered fatty acids and (iii)  odd numbered normal paraffins.

About $34\%$ of sunlight is reflected back out of the total amount of sunlight falling on earth. $10\%$ is absorbed by ozone and out of remaining $56\%$ only $0.02\%$ is used for photosynthesis.

Curing of tea leaves is accomplished by bacteria. Leaves of tea and tobacco are cured off their bitterness with the help of certain bacteria, e.g., Bacillus megatherium. Beans of coffee and cocoa are similarly cured.

Organic compounds like plant and animal residues are present in the soil. These organic compounds are broken down by a large number of bacteria, fungi, larger organisms. Bacteria like Pseudomonas lives in the soil and decomposes organic compounds and releases carbon dioxide, energy, water and other plant nutrients.
