A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Let’s evaluate each number:

  • 49: Divisible by 1, 7, and 49 (7 x 7), so it is not prime.
  • 69: Divisible by 1, 3, 23, and 69 (3 x 23), so it is not prime.
  • 29: Divisible only by 1 and 29. Therefore, it is prime.
  • 39: Divisible by 1, 3, 13, and 39 (3 x 13), so it is not prime.

Thus, the number classified as prime is 29.
