Yeah... you're right. Antibody dependent cell mediated cytotoxicity does not require complement to attack parasite. That is a right answer.

2.each of following statements about lymphocyte activation is correct expect one?
a.interleukin 5 is a B cell growth and differentiation factor
b.interleukin 2 stimulates proliferation of T and B lymphocytes
c.B lymphocytes recoginze antigen on surface of antigen-presenting cells in context of HLA-D moleules
d.T lymphocytes recognize ag on the surface of antigen presenting cells in context of HLA-B molecules

ans.d
The answer is "c"
IL 5 makes B cell to undergo class switching
IL 2 stimulates citotoxi T cell
MCH in humans, human leukocyte antigen (HLA), allow T cell to recognize antigen. There are 2 groups, depending on the class (I or II MHC):
Clase I.-
HLA-A
HLA-B
HLA-C
Clase II.-
HLA-DP
HLA-DQ
HLA-DR
So, there is not a HLA-D recognized antigen
