Let Q represent a set of two distinct prime numbers. If the sum of the numbers in Q is even and x is a member of Q, then what is the least possible value that x can be? Choose the correct option:
A) 1
B) 5
C) 3
D) 2
E) 7
Q = p1+p2= even (and all primes are distinct)   if the least prime is 2 then we have sum of Q =even.   Ans. D. 2
