D Correct answer
Explanation

The only even prime number is 2, and it is less than 16. There are 100 cards from 2 through 101, so the probability is 1/100.

AI explanation

The total number of cards is 100, as the numbers range from 2 to 101. The only even prime number less than 16 is 2, giving us 1 favorable outcome. Using the classical probability formula, the probability is 1 divided by 100. The result is 1/100.
