If A and B are two prime numbers bigger than 2, which of the following can't be true?
(1) A + B is an even number.
(2) A x B is also a prime number.
(3) A- B is also a odd number.
Choose the correct choice from the following choices:
A) 1 only. B) 2 only. C) 3 only. D) 1 and 3 only. E) 2 and 3. Only
(1) A + B is an even number. : All primes beyond 2 are odd, so odd+odd = even, so true   (2) A x B is also a prime number. : Beats the property of primes, so false   (3) A^B is also a prime number. : Beats the property of primes, so false   Ans 2 and 3. Only
