(D) The correct answer is $(d)$.Sound is a mechanical wave that requires a material medium (like air,water,or solids) to propagate.The moon has no atmosphere and is essentially a vacuum.Since there is no medium for the sound waves to travel through from the explosion site to an observer on the moon's surface,the sound will not be heard at all.

Sound Waves (Longitudinal wave) and it’s Characteristics (Speed etc.)

$A$ person standing between two parallel cliffs fires a gun and hears two echoes, the first echo after $1$ second and the second echo after $3$ seconds. The distance between the two cliffs is (The velocity of sound = $330$ m/s). (in $m$)
