If x and y are positive integers, and 3 is not a factor of y, then y may be which of the following?  Choose the correct choice from the following answers
A) (x−1)·x·(x+1)  B) (x−3)·(x−1)·(x+1)  C) (x−2)·x·(x+2)  D) (x−1)·x·(x+2)  E) (x−3)·(x+1)·(x+2)
Plugged in values :   let x=5   A. (x−1)·x·(x+1) --&gt; divisible by 3   B. (x−3)·(x−1)·(x+1) --&gt; divisible by 3   C. (x−2)·x·(x+2) --&gt; divisible by 3   D. (x−1)·x·(x+2) --&gt; not divisible. Hence the answer.
