Answer:

  E)  0

Step-by-step explanation:

You want to identify the value on the given list that is the product of three consecutive integers.

Product

If we let n represent the middle of the three integers, then we have ...

  product = (n -1)(n)(n +1) = n(n² -1)

Parity

We can see that when n is even, the product will be (even)×(odd) = even.

When n is odd, the product will be (odd)×(even) = even.

This eliminates choices B and D.

The zero product rule tells us that the product will be 0 if n=0, which is to say that the product of the consecutive integers -1, 0, 1 will be 0.

The product must have three consecutive integer factors, so cannot be 2 or 8. This eliminates choices A and C.

  8 = 1·2·4 . . . non-consecutive integers

  2 = 1·1·2 . . . non-consecutive integers
