Answer:
The correct answer will be option-A.
Step-by-step explanation:
Hormones act on the target cells of the body in two ways: antagonism and synergism.
The synergism is the condition when two or more hormones act on the same target cells to produce more strong and amplifies results than they achieve individually. The most common example of synergism in the body is the effect of the follicle-stimulating hormones (FSH) and testosterone on sperm production.
Thus, option-A is the correct answer.
