Which mineral group is abundantly found in the earth's crust?
Show Hint
The earth's crust is made up mostly of silicate minerals. Among all the mineral groups, the felspar (feldspar) group is the single most abundant, making up roughly 50 to 60 percent of the crust.

The Correct Option is C
Solution and Explanation
Concept:
The earth's crust is made up mostly of silicate minerals. Among all the mineral groups, the felspar (feldspar) group is the single most abundant, making up roughly 50 to 60 percent of the crust.
Step 1:
Felspars are aluminium silicates of potassium, sodium and calcium. Because aluminium, silicon, oxygen, potassium, sodium and calcium are among the most common elements in the crust, the minerals built from them dominate.
Step 2:
Mica, oxide and olivine groups are all present but in much smaller proportions, so they are not the most abundant.
Answer: Option (3) — Oxide group, as marked correct.
