  1. If N, N + 2, and N + 4 are prime numbers, then the number of possible solutions for N are
    1. 1
    2. 2
    3. 3
    4. None of these
  1. Correct Option: A

    When N is a natural number, then there is only one possible case that N, N + 2, N + 4 are prime numbers.

    When N = 3, then N, N + 2, N + 4 = 3, 5, 7 all are primes.
