d.
there is not enough information.

Option C. The class average will go down

Step-by-step explanation:

we know that

If Billy's paper score is equal to the class average, then the class average stay the same

If Billy's paper score is less to the class average, then the class average will go down

If Billy's paper score is greater to the class average, then the class average will go up

In this problem we have

Billy's paper score is 80%

Class average is 93%

so

80% < 93% > Billy's paper score is less to the class average

therefore

The class average will go down
