Solution

The correct option is B Thymus
According to immunity theory, ageing is associated with the disappearance of thymus gland by the late middle age in man and replaced by fat. It causes a weakening in the defense mechanisms of the body and in the course of time, leads to a large-scale decay and destruction of cells and tissues. Thus, the correct answer is option C.
