Answer: A


for statement 1, we can take x=0 which will make it even.
hence answer should be E

If x is 0, then 11/x would be undefined and not an integer (division by 0 is not allowed). So, x cannot be 0.

Bunuel, please correct my (mis)understanding of the DS options:

Option A means to say that Statement A is sufficient to answer the question, so although statement A shows that x=uneven number, and albeit the question asks whether x is an even number, we can conclude that x is not even from statement A. Hence this is more a statement of sufficiency rather than the actual answer itself.

Thank you for your help.

Yes, a definite NO answer to the question is still considered to be sufficient.

Isn't 0 an integer too?
An even integer. That's why I marked the first statement as insufficient.

Please clear this for me.

x cannot be 0 in (1) because it says that 11/x is an integer. Recall that division by 0 is not allowed, so if x were 0, then 11/x would be undefined and not an integer.
