    Answer: The correct option is A.

    Explanation:

    Loudness is the measure of the intensity of the sound wave. Intensity is the measure of the amount of energy. The unit of the intensity is decibel.

    The loudness of the sound depends on the amplitude.

    More the amplitude of the sound, more will be loudness. Lower the amplitude of the sound wave, softer will be the sound.

    Therefore, the subjective measurement of the intensity of sound describes the loudness.
