You are familiar with the concept of weight: the force on an object, near or at the surface of the earth, due to its gravitational interaction with the mass of the earth. Using this observation, and applying the third law to this case, we conclude that this object exerts a force on:
1. Itself.
2. On the moon.
3. On the earth.
4. On the air that surrounds it.
5. On the seas (the type of force that gives rise to tides).
5. On the sun.
6.On the ground that supports the object.
I picked "6", but I am not sure.

I think the asker wants you to answer 3, on the earth.
The hint is the use of newton's third law, which says that for every action force there is an equal and opposite reaction force. So if the earth exerts a force on you, you exert an equal and opposite force on the earth.

I would say 3. Earth since the question uses the word Earth, and not ground.
But frankly I don't see a difference between 3. and 6. It's just semantics.
