    The correct answer is D. 2200 Hz

    Explanation:

    The frequency of a wave is measured in hertz (Hz) and refers to how often a wave passes through a point during a specific time. This factor can be calculated if you divide the velocity of the wave by the wavelength (distance between crests) this means f (frequency) = v (velocity) / λ (wavelength).

    f (frequency) =  242 m/s (velocity) / 0.11 (wavelegth)

    f = 2200 Hz

    According to this, the frequency of the wave, in this case, is 2200 Hz
