Detailed Solution

Lymphocytes are produced in the bone marrow; the primary lymphoid organs, where immature lymphocytes differentiate into antigen-sensitive lymphocytes, are the bone marrow and the thymus.
The lymphocytes that migrate to the thymus and mature there are called T-lymphocytes; 'T' stands for thymus.
The lymphocytes that mature in the bone marrow are called B-lymphocytes.
The thymus is a lobed organ located near the heart, beneath the breastbone; it is large at birth and reduces with age.
Hence the letter T refers to the thymus.
