Yes, because the frequencies start low, proceed to one or two high frequencies, then increase to a maximum, and the distribution is not symmetric.O B. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximatelysymmetric.O 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.O D. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximatelysymmetric.
