If n=1+x, where x is a product of four consecutive positive integers, then which of the following is true?
A. n is odd
B. n is prime
C. n is a perfect square
Since xx is the product of four consecutive integers, it is always divisible by 4, i,.e., it is always even. So, 1+x is always odd.
So, 1+x is a perfect square as we can see. Hence, option A is the correct choice.
