I need help with one more question.

A. 100 percent
B. 50 percent
C. 25 percent
D. 0 percent
Is the answer C?

I agree with c.

No offense but you should study for the test instead of posting a question. I mean when the state test comes up this year or next year (depending on where you live) you will fail horribly.
