Stmnt 1 > A is a perfect square and is square of integer B
So A will always have the same number of unique prime factors as B
Sufficient
Stmnt 2 > A> B
Sample 1
A=7 B= 5 > Both have same number of same unique prime factors
A=6 B =2 > A has more number of unique prime factors than B
So Ans A
So A will always have the same number of unique prime factors as B

Sample 1
A=7 B= 5 > Both have same number of same unique prime factors
A=6 B =2 > A has more number of unique prime factors than B
