Model Answer
(A) Both (A) and (R) are true and (R) is the correct explanation of (A).

The textbook directly states that aluminium is light, resistant to corrosion, and becomes strong when mixed with other metals — and that these properties have made it a popular substitute for steel, copper, zinc and lead. So (R) directly explains (A).
