    Observers ahead of the wave observe an apparent increase in wave frequency

    Explanation:

    This is the Doppler Effect. The frequency of a wave increases when the source approaches the observer and decreases as the source recedes.

    B, C, and D are wrong. Observers behind the source notice a decrease in frequency.
