Cattle farming is one of the methods of animal husbandry that is most beneficial for farmers.

Using this method:

● Better breeds of draught animals can be produced. Such draught animals are engaged in agricultural fields for labour work such as carting, irrigation, tilling, etc.

● Good quality and quantity of milk can be produced.

● They are raised for obtaining meat.

Hence A is correct.

Since cattle’s can not lay eggs, they directly give birth to theirs offspring’s hence they cannot be used for egg production; instead poultry farming is done to produce eggs.
