Refer to the two statements given below and choose the CORRECT option.
Statement A: Milch animals are reared primarily for the production of milk.
Statement B: Milch animals are mainly used for ploughing agricultural fields.

The correct option is: Statement A is correct but B is incorrect.

To understand why this option is correct, let us analyze both statements one by one:

Analysis of Statement A:
Milch animals are domestic animals that are kept and reared primarily for producing milk. Examples of milch animals include cows, buffaloes, goats, and camels. Since the statement states that milch animals are reared primarily for milk production, Statement A is correct.

Analysis of Statement B:
Animals used for agricultural labor, such as ploughing fields, pulling carts, and transporting heavy loads, are referred to as draft (or draught) animals. Examples include oxen, bullocks, and horses. Milch animals are not primarily used for such heavy physical labor like ploughing. Therefore, Statement B is incorrect.

Conclusion:
Since Statement A is correct and Statement B is incorrect, the option "Statement A is correct but B is incorrect" is the accurate choice.
