What causes T cells to become immunocompetent by secretion of thymosin & thymopoietin
A
spleen
B
lymph nodes
C
lymphatic vessels
D
thymus
Explanation: 

Detailed explanation-1: -Thymopoietin: fuels the production of T-cells and tells the pituitary gland to release hormones. Thymosin and thymulin: help make specialized types of T-cells. Thymic humoral factor: keeps your immune system working properly.

Detailed explanation-2: -The thymus gland is the primary lymphoid organ for lymphocyte development. The red bone marrow produces B-lymphocytes (B cells) and T lymphocytes (T cells). B cells achieve immunocompetence (ability to recognize a specific antigen) in bone marrow. T cells migrate to the thymus gland, where they become immunocompetent.

Detailed explanation-3: -Thymus. The thymus is an immune organ controlling the development of lymphocytes. It also produces thymopoietins and thymosins, which are hormones important to the immune system (Wilson, 2009).
