Sectio A comprises of 0 questios of oe mark each. Sectio B comprises of questios of four marks each ad Sectio C comprises of 7 questios of six marks each. There is o overall choice. However, a iteral choice has bee provided i questios of four marks each ad questios of six marks each. You have to attempt oly oe of the alteratives i all such questios. SECTION A.
