A, B, and D are equal to 75%

Step-by-step explanation:

Hope it helps!

B., A.  and D.

Because they all equal 75%!

The correct option is: Option (B) Trevor isn't correct because -2i must also be a root

Explanation:
The roots given are: -7, 2i, +7.

We need to differentiate between the real roots and the imaginary roots.

The real roots are: -7 and +7.
The imaginary root given is: 2i

However, the imaginary roots ALWAYS come in pair like 
Because the imaginary roots come from the square root; In this case, the roots might be in the form of: . The square-root of the negative number yields the imaginary numbers (which can be positive or negative), which in this case is +2i and -2i.

Hence the correct answer is that Trevor isn't correct because -2i must also be a root (Option b).
