An even number is defined as any integer that is divisible by 2 without any remainder. In this case, 14 is the only number in the options provided that meets this criterion. When you divide 14 by 2, the result is 7, which is an integer with no remainder.

In contrast, the other options (7, 11, and 21) are all odd numbers, as each of these numbers divided by 2 results in a fraction or a remainder. Recognizing the characteristics of even and odd numbers is crucial for solving similar problems efficiently.
