Sagot :

We will have the following:

*We can see that 2 is part of the set and 2 is not greater than 2, so option A is not the solution.

*We can see that 5 and 10 are divisible by 5, so option B is not the solution.

*We can see that the numbers 2, 4, 6, 8 & 10 are even but the others are odd. The remaining are less than 12, thus option C is the solution.
