I believe that the correct answer is c. The boundaries of earth's plates. This is because when the plates move the mantle seeps out through the gaps the previous plate had been at this is also called seafloor spreading because as the mantle seeps up it forms new crust that pushes the other plates further apart
The acceleration on surface of moon =1.67m/s^2
Weight =mass ×acceleration
=7×1.67
=11.69N
