It looks like A

If the three positive integers are consecutive, they must include one that is divisible by 3. Therefore their product is also divisible by 3.

2 is insufficient.

If zero was defined as a positive integer, things might be different, but I think I recall reading that zero is defined as neither negative nor positive. Is this right?

the OA is indeed A

As for your question - zero is neither negative nor positive and 0 is divisible by 3.
