Astronauts on the moon can jump higher than if they were on earth. this is a. newton's laws of motion do not apply to the moon. b. the moon is less massive than the earth. c. there is no friction on the moon. d. the astronauts are less massive on the moon.

It'll be B) The moon is less massive than the Earth

Mass relates to how much gravitational pull something has.
Since the moon is significantly less massive than the moon it inherently has less gravity than on Earth thus allowing the astronauts to jump higher on the moon than on Earth
