Correct answer: D. Both a and b
- A. Cryolite
- B. Fluorspar
- C. Dolomite
- D. Both a and b
Explanation
Both Cryolite (Na₃AlF₆) and Fluorspar (CaF₂) are important ores of fluorine. Cryolite is primarily used in the production of aluminum, while fluorspar is a key source of fluorine for various industrial applications, including the production of hydrofluoric acid.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
