the ans is ...
statement one: X is a perfect square... which means that X has a number lets suppose 'y' that multiplied into itself will give rasie to X
ex ---- > y * y= X, y=2 so , 2*2=4=X...now X can never be a prime 'cos it does have another integer which can divide X apart from X and the number 1 ( which is the sloe requisite of a prime number !)
B-> says X ^2 is a prime number and now we got all the number s which fulfill this nescessity...we got 2 to satisfy this condition as well 4 too... which is not a prime whereas the number 2 is . not sufficient
the whole worldmakes way for the man who knows wer he's going... good luck
