Question

In the question given below, there are two statements marked as Assertion (A) and Reason (R). Read the statements and choose the correct option: Assertion(A): Bauxite is the main ore of aluminium.
Reason(R): Bauxite deposits are formed by the decomposition of rock rich in aluminium silicates.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true but R is not the correct explanation of A
(c) A is correct but R is wrong
(d) A is wrong but R is correct

Answer 1

Answer:

Both are true with correct explanation

Answer 2

(a) Both A and R are true and R is the correct explanation of A

Explanation:

Assertion (A): Bauxite is the main ore of aluminium. The ore is chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. So Assertion A is correct.

Reason (R): Bauxite deposits are formed by the decomposition of rock rich in aluminium silicates. Bauxite is typically found in topsoil located in various tropical and subtropical regions. So Reason R is correct.

Option A is correct.
