Solution

The correct option is C
The factors of 10 are: 1, 2, 5, and 10
The factors of 9 are: 1, 3, and 9
The factors of 2 are: 1 and 2
The factors of 4 are: 1, 2, and 4

Prime numbers are numbers with only two factors: 1 and the number itself.

Thus, 2 is the only prime number in the list, and its only two factors are 1 and 2.

Hence, the correct option is 2 of hearts.
