Lunar soil (regolith) primarily contains which of the following compounds?

SiO₂ (Silicon dioxide)

CaCO₃ (Calcium carbonate)

Fe₂O₃ (Iron(III) oxide)

NaCl (Sodium chloride

Lunar soil is composed mainly of silicate minerals, with silicon dioxide (SiO₂) being a significant component.

Other components include various metal oxides like Fe₂O₃ and MgO, but SiO₂ is prevalent in the overall composition.

Calcium carbonate (CaCO₃) and sodium chloride (NaCl) are not typically found in lunar soil.
