In short... it's testing our number sense.

Let's start with a positive number.

The easiest number to choose is 1.

Multiply 1 by itself 4 times... and we get 1.

Now let's try a negative number.

We're going to be insanely creative and pick... negative 1.

Multiply it by itself 4 times and we get...

-1 times -1... that's positive 1. Times -1 is negative 1. Times -1 again is positive 1.

Now we know that both the positive and negative cases will give us a positive answer.

We've only got one number left to try. Multiply by 0.

0 by 0 by 0 by 0... it's just 0

Never going to be anything different.

When we tested these three cases, we saw that

the only possible outcomes were a positive number or 0.

The answer is B. As in, "Boo."
