Question #2
Consider statements about animal husbandry: 1. Poultry provides eggs and meat. 2. Apiculture increases crop yield. 3. Dairy farming focuses on fish production. Which are correct?
A. 2 and 3 only
B. 1, 2 and 3
C. 1 and 2 only
D. 1 and 3 only

Correct Answer: Option C


Explanation:
Poultry farming involves rearing birds like chickens for the production of eggs (layers) and meat (broilers). Apiculture (beekeeping) not only produces honey but also significantly increases crop yields through enhanced pollination by bees. Dairy farming focuses on the breeding and rearing of cattle, buffaloes, etc., for milk production, not fish (which is pisciculture). Thus, statements 1 and 2 are correct.
