Verified step by step guidance

Step 1: Understand the role of T lymphocytes in the immune system. T lymphocytes, also known as T cells, are a type of white blood cell that play a critical role in adaptive immunity by identifying and attacking pathogens.

Step 2: Review the function of the thymus gland. The thymus is an organ located in the chest that is responsible for the maturation and differentiation of T lymphocytes. It produces specific hormones to support this process.

Step 3: Identify the hormone associated with the thymus gland. Thymosin is a hormone secreted by the thymus that stimulates the production and maturation of T lymphocytes.

Step 4: Compare the other options provided in the question. Erythropoietin is involved in red blood cell production, insulin regulates blood glucose levels, and cortisol is a stress hormone that affects metabolism and immune response. None of these are directly involved in T lymphocyte production.

Step 5: Conclude that thymosin is the correct answer based on its specific role in stimulating the production of T lymphocytes in the thymus gland.
