Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. A is false, but R is true.
The assertion is incorrect because Iron and Steel is the most important metallurgical industry in India, serving as the "backbone" of all other industries. Aluminium smelting is actually the second most important metallurgical industry. However, the reason is correct; aluminium is highly valued because it is light, resistant to corrosion, and a great conductor of heat and electricity. These properties make it indispensable for manufacturing aircraft, electrical wires, and kitchen utensils.
