If a is a positive integer, then a(a+1)(a+2) is Choose one.
A) even only when n is odd B) odd whenever n is odd C) divisible by 3 only when n is odd D) divisible by 4 whenever n is even E) even only when n is even
a*(a+1)*(a+2)= +ve even integer divisible by 4 ( e.g 6,7&amp;8)   divisible by 4 whenever n is even
<result>D</result>
If a is a positive integer, then a(a+1)(a+2) is
