If n = 1+x where x is the product of four consecutive positive integers, then which of the following is/are true?
A. n is odd
B. n is prime
C. n is a perfect square
Let us take x=1×2×3×4=24
Then n=1+24=25
i.e.
an odd number and a perfect square
Again let x=2×3×4×5=120.
Then, n=1+120=121
i.e.
an odd number and a perfect square
∴ Option (A) is correct
