Ghost Of Highbury:
Ur welcome.

Malak:
How come the answer is D?

Ghost Of Highbury:
If they were on earth, he wud hear the loud sound. but in space, he cant hear it, so no sound at all. Sound needs a medium to travel, in space, theres vacuum, no air particles, thus no sound.

WARRIOR:
SOUND = VIBRATION OOF MOLECULES


NO AIR IN THE MOOOOOOOOOON  ( NO MOLECULES )

NO VIBRATION

Malak:
