Which of the following numbers is an odd number?

• A. 2
• B. 4
• C. 7
• D. 10

Answer: (C)

An odd number is defined as an integer that is not divisible by 2, meaning when divided by 2, it leaves a remainder of 1. In the provided choices, the number 7 meets this criterion because when divided by 2, it results in 3 with a remainder of 1. The other numbers—2, 4, and 10—are even numbers because they can all be evenly divided by 2, yielding whole numbers without any remainder. This distinction is essential in identifying odd numbers within a set of integers. Thus, 7 stands out as the only odd number among the options given.
