Options :
  1. Feldspar
  2. Bauxite
  3. Cryolite
  4. Azurite
Answer and Explanation :-

Answer: Option 4


Feldspar is a name given to a class of aluminium-containing silicates which are sometimes called light silicates or "nonferromagnesian silicates" since they don't contain iron or magnesium. Bauxite, an aluminium ore, is the world's main source of aluminium. Cryolite is an uncommon mineral that was historically used as an ore of aluminium and later in the electrolytic processing of the aluminium-rich oxide ore bauxite. Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits.
