Is \(x^2 > x\) ?
(1) x is a prime number
(2) x ≥1
i) x is prime ,so x can be 2,3 ,5,7...
Let x=2
So x^2 =4
4>2
So sufficient
ii) x>=1
So let x=1
So x^2=1
1 is not greater than 1
So not sufficient

statement 1
x is a prime number
X^2> X is possible in every case
statement 1 is sufficient
statement 2

there are two cases
hence statement two not sufficient
answer is A option
