Answer:

B) The frequency of the sound is 100 Hz.

Explanation:

Frequency of the sound is always equal to the frequency of the source

So here we know that

length of the string is

L =0.6 m

Speed of the sound is

v = 340 m/s

frequency of the sound

f = 100 Hz

now the wavelength of the sound is given as

\lambda = \frac{v}{f}

\lambda = \frac{340}{100}

\lambda = 3.40 m
