Step 1: Identify what bauxite is.
Bauxite is the raw ore from which aluminium is extracted.
Step 2: Check if it contains iron.
Since aluminium has no iron content, bauxite falls outside the ferrous group and belongs with minerals like copper, lead, and zinc.
Step 3: Rule out the other categories.
It is not an energy mineral like coal or petroleum, not a non-metallic mineral like mica or gypsum, and not counted among precious minerals like gold or diamonds.
Step 4: Conclude.
The correct answer is option (C), Non-Ferrous Minerals.
