For every positive even integer n, the function h(n) is defined to be the product of all the even integers from 2 to n, inclusive? If p is the smallest prime factor of h(100)+1, then p is:
A)between 2 and 10
B)between 10 and 20
C)between 20 and 30
D)between 30 and 40
E)greater than 40

I don't really get what the question is asking. I know it's to find p, but how? Thanks for any help!!!
