Right answer is (c) It is intact for persons of all ages

Easiest explanation: Thymus is an endocrine gland situated between the lungs and behind the sternum. It secretes thymosin and the differentiation of T-lymphocytes takes place here. It promotes antibody production. However, the thymus degenerates in old individuals.
