The correct answer is A. hormones.
Farmers often use hormones to promote faster growth in chickens during confinement. These hormones can stimulate muscle growth and increase feed efficiency, leading to larger and heavier birds in a shorter time span. However, it’s important to note that the use of hormones in poultry farming is not permitted in many countries due to health and safety regulations.
