Thymosin is a hormone that plays a significant role in the immune system. It is produced by the thymus gland and enhances the development and differentiation of T-lymphocytes (T-cells), which are vital for the adaptive immune response. By stimulating the maturation of T-cells, thymosin helps in effectively mobilizing the immune response to pathogens and is crucial for maintaining overall immunity.

Given the options provided:

a. The rate of metabolism - This is primarily influenced by hormones like thyroid hormones, not thymosin.

b. Body growth - While thymosin might have some indirect effects related to immune health, it is not primarily known for regulating body growth.

c. Immunity - Correct! Thymosin directly influences the maturation and function of T-cells, making it vital for immunity.

d. Maintaining early pregnancy - This is typically regulated by hormones like progesterone, not thymosin.

Therefore, the correct answer is c. Immunity.
