To determine which of the given numbers is prime, we need to check whether each number has exactly two distinct positive divisors: 1 and itself.

  1. 27: The divisors are 1, 3, 9, and 27. (Not prime)
  2. 54: The divisors are 1, 2, 3, 6, 9, 18, and 54. (Not prime)
  3. 69: The divisors are 1, 3, 23, and 69. (Not prime)
  4. 95: The divisors are 1, 5, 19, and 95. (Not prime)
  5. 97: The only divisors are 1 and 97. (Prime)

The only prime number among the choices is 97 (Choice E).
