Both Earth's Moon and Mars Have Thick Layers of Loose

Both Earth's Moon and Mars have thick layers of loose surface materials. How are they different?

A) They are different. Lunar regolith is mostly ejecta from impacts whereas Martian regolith is primarily wind- blown dust and sand on older surfaces that vary from water laid surfaces to volcanic surfaces.
B) They are not different. They are both comprised primarily of ejecta from impacts that accumulates on the surface.
C) They are not different. Both have surfaces that are remnant soils from a period when they had water on the surface.
D) They are different. Lunar regolith is mostly ejecta from impacts, whereas Martian soil is more earthlike with classic soils developed by weathering of rock.
