true mayank
its really annoying and on top of that we tend to waste a lot of time on the q like that ....... and its not that its due to a printing mistake coz we keep on getting the same wrong answers in the other papers too if the question gets repeated......hope anything could be done about that coz these may be misleading if we dont know the answers by ourselves
how about ur preparation?is it goin well ......i know there must be a lot of anxiety as the paper gets near but no worries 4 u i feel as u r confident enough in ur studies .....
good luck

thymic hypoplasia may result in
a. hypergammaglobulinemia
b. decreased propensity to develop cancer
c. an increased predisposition to fungal and viral infections
d. absence of plasma cells

ans. is (c) and (d) acc. to the key
thymic hypoplasia is digeorges syndrome right.....so there is defective development of thymus gland and parathyroids....
so the T lymphocytes will not mature and resultant predisposition to viral and fungal infections but how is the absence of plasma cells in this condition
can u pls clarify this answer

The Helper "T" cell count is also decreased (along with other T cells) in thymic hypoplasia. The helper T cells stimulates the production of PLASMA cells from B cells.

So plasma cell count is also decreased in thymic hypoplasia. (And therefore, hypo-gammaglobulinemia!)
