(B) The time period of one vibration is $T = 1/n$,where $n$ is the frequency.For $32$ vibrations,the total time taken is $t = 32 \times T = 32/n$.The distance travelled by sound in this time is $d = v \times t$,where $v$ is the velocity of sound.Substituting the values: $d = v \times (32/n) = 344 \times (32/256)$.$d = 344 \times (1/8) = 43 \, m$.
