D Correct answer
Explanation

The numbers from 90 to 100 inclusive are 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 (total 11 numbers). Among these, only 97 is a prime number. Therefore, the probability is 1 out of 11. Other options assume a total of 10 numbers, which is incorrect for an inclusive range.
