    Bhaiya, in PAPER2 Q11(ASSERTION REASON) ANS IS GIVEN AS B BUT I THINK IT SHOULD BE A.IN SOLN,IT IS GIVEN THAT WE NEED NOT USE STAT 2 PROVING STATEMENT1 .I AGREE.BUT IF WE USE STATEMENT 2, THEN WE ARE ABLE TO REACH TO STATEMENT1 (I.E.WHAT WE HAVE TO PROVE IN STATEMENT 1).STATEMENT2,IN FACT,IS ANOTHER WAY OF WRITING THE GIVEN PART OF STATEMENT1 I.E.WE CAN DEDUCE GIVEN PART OF STATEMENT1(WHICH IS FURTHER USED IN PROVING “TO PROVE” PART IN STATEMENT1) FROM STATEMENT2 .HENCE, IN ANY CASE IT IS ABLE TO EXPLAIN STAT 1. SO IT CAN’T BE TERMED AS INADEQUATE OR INCORRECT EXPLANATION TO STAT 1.
    SO PLEASE REVIEW THE SOLUTION TO THIS Q.
