    D)  loss of antibody-mediated immunity

    Correct Answer: A

    Solution :

    Thymus is the seedbed of thymic lymphocytes (T-lymphocytes). Some stem cells in the bone marrow give rise to immature lymphocytes. These lymphocytes migrate via the blood to the thymus, where they mature as T-lymphocytes, they produce cell-mediated immunity. Thus, damage to thymus in a child may lead to loss of cell-mediated immunity.
