B)32
C)16
D)8
E)6

To determine the number of bits required, we use the formula $2^n = \text{number of levels}$, where $n$ is the number of bits. For 64 amplitude levels, $2^n = 64$, solving for $n$ gives $n = 6$. The sampling rate (4000 times per second) does not affect the number of bits needed to represent each sample, only the number of samples taken per second.
