Explanation

Both A and R are true, but R is not the correct explanation of A.

Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which filters aluminum from the bauxite.

R tells the location, but not the reason for Bauxite being the main ore of aluminium.
