If a+5/b is a prime integer, which of the following must be true?
1.b=5a
2. b is a prime integer
3. a+5/b is ODD.	Choose the correct choice:
A) None	B) 1 only	C) 2 only	D) 1 and 2 only	E) 2 and 3 only.
I would pick up numbers and do .   i hope the question is (a+5)/b....   let a = 3 , b = 4   3+5/4 = 2 = Prime   1. b is not equal to 5a   2.b is not a prime number   3. (a+5)/b is not odd.   hence None
