Choose the correct answer below.

A.

?Yes, because the frequencies start? low, proceed to one or two high? frequencies, then increase to a? maximum, and the distribution is not symmetric.

B.

?No, because the frequencies start? low, proceed to one or two high? frequencies, then decrease to a low? frequency, and the distribution is approximately symmetric.

C.

?No, because the frequencies start? low, proceed to one or two high? frequencies, then decrease to a low? frequency, and the distribution is not symmetric.

D.

?Yes, because the frequencies start? low, proceed to one or two high? frequencies, then decrease to a low? frequency, and the distribution is approximately symmetric.
