[C] 3 only

[D] All of the above

Answer: A

Notes:

Cotton is also a water intensive crop. Following are the Typical Crop water requirement (in litres) per kilogram of crop. For Cotton 7,000 – 29,000 and for Sugar Cane it is 1,500 – 3,000.
The No Till system is very effective to increase soil water infiltration, to reduce evaporation from soil and also to reduce water run-off. The water availability for crops is increased. The savings in soil moisture can be just as important, especially in a year when soil moisture and precipitation are short or when irrigation is costly or water supplies are limited.
