Which of the following is a prime number?
  1. 50
  2. 25
  3. 23
  4. 6
Explanation
Answer: C - 23 is a prime number. A prime number is a number that can only be divided by itself and by the number 1, without a remainder. 50, 25, and 6 can all be divided by numbers other than itself and 1. Even numbers greater than 2 are never prime.
