The primary minerals found in basalt are:

Correct option is B

The correct answer is (b) FeO and MgO.
FeO (Iron(II) oxide) and MgO (Magnesium oxide) are the primary minerals found in basalt.
Basalt is a mafic igneous rock, and it is rich in iron and magnesium.
The presence of FeO and MgO gives basalt its dark color and dense composition.
Basalt forms from the rapid cooling of low-viscosity lava and is commonly found in oceanic crust.
Information Booster:
CaCO₃ (Calcium Carbonate) & Na₂CO₃ (Sodium Carbonate): These minerals are not major components of basalt. CaCO₃ is found in sedimentary rocks like limestone, and Na₂CO₃ is used in industrial applications.
SiO₂ (Silicon Dioxide) & K₂O (Potassium Oxide): SiO₂ is present in rocks like granite, while K₂O is found in feldspar minerals. They are not the main components of basalt.
CaSO₄ (Calcium Sulfate) & NaCl (Sodium Chloride): These compounds are not associated with basalt. CaSO₄ is found in gypsum, and NaCl is common salt, neither of which are primary in basalt.
