Hey,
Sorry to bring this back up again, but I still do not get why the answer is D and not A
I will just take a look at the second statement, as I do understand why the first Statement is sufficient.
(2) Y<3 => okay because x & y are prime numbers, and Y is less than 3 => y=2
So far so good, now, if we put Y into the equation, the equation will look something like this
2(x-3)
So we know, that X is a prime, Statement 2 would always be sufficient except when X=3
2(3-3)=0
The question stem asks if the outcome for the equation is odd, afaik 0 is neither. So how can the statement be sufficient? What am I not seeing?
Best regards!

Note that 0 is an even number, so y(x-3) will be even even if x = 3.
ZERO.
1. 0 is an integer.
2. 0 is an even integer. An even number is an integer that is "evenly divisible" by 2, i.e., divisible by 2 without a remainder and as zero is evenly divisible by 2 then it must be even.
3. 0 is neither positive nor negative integer (the only one of this kind).
4. 0 is divisible by EVERY integer except 0 itself.
