Correct answer: A
Answer: The assertion is true and the reason is false.
Explanation: White clothing is advised in summer because white surfaces reflect most of the sun's visible radiation and therefore absorb less energy, keeping the wearer cooler. The reason statement is incorrect because it claims white absorbs maximum sunlight; in reality, darker colours absorb more sunlight and convert more of it into heat.
White reflects a large portion of incoming sunlight (high albedo), so less light is absorbed as heat.
Darker colours absorb more wavelengths of sunlight and heat up more, making them less comfortable in hot weather.
Practical note: fabric type, weave, and ventilation also affect how hot clothing feels, but colour has a major influence on absorption versus reflection of sunlight.
