Cantilevered beam

The bending moment in a cantilevered beam is negative. Which of the following statements are true?
A. the top fibers are in compression
B. the bottom fibers are in compression
C. rebar placement should be either at the top or the bottom
D. gravity loads are not a factor for negative moment
AnswerB. the bottom fibers are in compression in a cantilevered beam, so top fibers are in tension which requires rebar placement at the top to resist tension.
