c. Thymus
The thymus gland is primarily responsible for the differentiation of T lymphocytes, a type of white blood cell involved in the immune response. The thymus is a specialized organ located in the chest and is crucial for the development and maturation of T cells, which play a critical role in recognizing and fighting off infections and abnormal cells in the body. As T cells mature in the thymus, they acquire specific receptors that allow them to recognize and respond to foreign antigens, helping to protect the body from various pathogens and diseases.
I hope this helped!
