Answer 1

The correct option is A a, b, c & d

Immature lymphocytes differentiate into antigen sensitive lymphocytes in bone marrow and thymus. Thymus provides a microenvironment for the development and maturation of T-lymphocyte. Thymus and bone marrow provide the sites of interaction of lymphocyte with antigen. Bone marrow act as a filter of the body by frapping bloodborne microorganisms.

So the correct option is 'a, b,c & d.'
