Answer: D. Milk and egg production
Step-by-step explanation:
Agriculture is a process of growing crops for fulfilling the demand of food for large human population.
Some of the fodder and roughage produced after the harvest of crops like wheat, barley, and maize can be useful for feeding milk yielding cattles like sheep, goat and cow. This increases the milk yield. Also the grains from these plants are used to feed birds in poultary farms. Healthy birds can yield good and healthy eggs which are edible. This way agriculture is beneficial for yielding milk and eggs.
