H(100) = (2*4*6*8*....*100) = ((2^50)*(1*2*......*50)) = (2^50)*(50!).
So all the prime number from 2 to 50, would divide (2^50 * 50!).
Thus none of the numbers between 2 and 50 would NOT divide [(2^50)*(50!) + 1] as they will always leave a reminder of 1.
Therefore, the required prime number would be greater than 50.
The correct answer is E.
