An object on the moon would weigh the LEAST among these. So correct answer is B.
Explanation:
Weight of an object on any place is given by:
W = Mass * Acceleration due to gravity(g)
It means when masses of different objects those are in different places are same, the weight of those objects depends upon the 'g' of that particular place.
As we know, acceleration due to gravity on surface of moon (g') is 6 times weaker than the acceleration on surface of earth (g), which is due to the large M/R^2 of the earth than the moon.
i.e. g' = g/6 so W' = W/6
And in the space between the two, the object is weightless.
