Match the following.

	Column I (Ores)		Column II (Formula)
(A)	Fluorspar	(p)	Al2O3.2H2O
(B)	Cryolite	(q)	CaF2
(C)	Bauxite	(r)	MgCO3.CaCO3
(D)	Dolomite	(s)	Na3[AIF6]

The correct option is (A)-(q); (B)-(s); (C)–(p); D-(r).

Let us match the ores listed in Column I with their corresponding chemical formulas in Column II:

(A) Fluorspar:
Fluorspar (also known as fluorite) is a mineral composed of calcium fluoride.
Therefore, Fluorspar corresponds to (q) ${\mathrm{CaF}}_2$.

(B) Cryolite:
Cryolite is an uncommon mineral identified as sodium hexafluoroaluminate. It is widely used in the electrolytic production of aluminum.
Therefore, Cryolite corresponds to (s) ${\mathrm{Na}}_3\left[{\mathrm{AlF}}_6\right]$.

(C) Bauxite:
Bauxite is the principal ore of aluminum, consisting largely of hydrated aluminum oxides.
Therefore, Bauxite corresponds to (p) ${\mathrm{Al}}_2{O}_3·2H_{2}O$.

(D) Dolomite:
Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate.
Therefore, Dolomite corresponds to (r) ${\mathrm{MgCO}}_3·{\mathrm{CaCO}}_3$.

Matching these together gives:
(A) - (q)
(B) - (s)
(C) - (p)
(D) - (r)
