\qquad\qquad\huge\underline{{\sf Answer}}

If two similar waves are traveling in the same medium, then they have same wave velocity. so we can infer that

\qquad \tt \dashrightarrow \:v_A = v_B

Now, as per the formula ~ we know that :

\qquad \sf \dashrightarrow \:v =   \lambda \cdot  f

  • v = wave velocity

  • λ = wavelength

Now, we can write it as :

\qquad \sf \dashrightarrow \: \lambda_A \cdot f_A =  \lambda _B \cdot f_B

And it's also given that frequency of wave A is 3 times that of frequency of wave B.

So, let's add the relation to our equation ~

\qquad \sf \dashrightarrow \: \lambda_A \cdot3f_B =  \lambda _B \cdot f_B

\qquad \sf \dashrightarrow \: \lambda_A \cdot3=  \lambda _B

\qquad \sf \dashrightarrow \: λ_A =  \frac{1}{3}  λ_B

So, choice C is correct ~
