The correct solution is option A "10 meters".

Explanation:

The given values are:

Wave X,

Frequency,

$F_x=200 \ H_z$

Wavelength

$\lambda_x=35 \ m$

Wave Y,

Frequency,

$F_y=700 \ Hz$

Let its wavelength = $\lambda_y$

As we know,

⇒ $v=f \lambda$

For both waves, medium is same then

⇒ v_x=v_y

⇒ $f_x \lambda_x=f_y \lambda_y$

then,

⇒ $\lambda_y=\frac{f_x \lambda_x}{f_y}$

On substituting the estimated values in the above equation, we get

⇒ $=\frac{200\times 35}{700}$

⇒ $=\frac{7000}{700}$

⇒ $=10 \ m$
