Let's rule out the options
A. Since product can be 0, one or more integers can be 0. Reject
B.At least two of the integers are even integers.
It may be true, but must not be true.
C. At least two of the integers are odd integers.
It may be true, but must not be true.
D. None of the integers is an odd integer.
It may be true, but must not be true.
E.Not all of the integers are odd integers.
This must be true since if all the integers are odd, product will be odd. Atleast one of the integers must be even.
Option E is the answer IMO

Sir Bunuel, please post official answers too, if you have the time.
Really appreciate you taking the time to post the questions, but just that we need to have some source to validate our answers too.
TIA!
