I had been asked this question by my school principal while I was bunking the class.

Origin of the question is Engine Performance Characteristics topic in portion Measurements and Testing/Performance Parameters and Characteristics of IC Engine

Answer 1

The correct answer is:

(d) brass

Radiator tubes are generally made of brass because it has good thermal conductivity, is corrosion-resistant, and has a high resistance to the effects of heat and pressure commonly found in cooling systems. Brass also offers a good balance between durability and cost, making it an ideal material for use in automotive radiators.
