1)- b
2)- a
3)- c ( Actually IgM and IgD both are present on the surface of B Lymphocyte but primarily IgM is the first antibody that generated at the time of defence.)
4)- c
5)- b ( T Cell Receptor is a heterodimer)
6)- a ( MHC type I antigen present on almost all cells except red blood cells while MHC type II can be found on antigen presenting cell, dendritic cells, B cells, Macrophages etc)
