Directions: Read the Assertion (A) and Reason (R) carefully and choose the correct alternative. Assertion (A): We generally prefer to wear white clothes in winter. Reason (R): White clothes are good reflectors of heat and do not absorb much radiant heat.

Introduction / Context:
This question checks basic understanding of heat absorption and reflection by different coloured clothes. It uses the Assertion and Reason format to see whether you know which colours are preferred in summer and winter, and why. Clothing colour and comfort in different seasons is an everyday practical application of physics concepts related to absorption and reflection of radiant heat.

Given Data / Assumptions:

• Assertion (A) claims that people generally prefer to wear white clothes in winter.
• Reason (R) states that white clothes are good reflectors of heat.
• It is well known that black and dark coloured surfaces absorb more radiant heat, while white and light coloured surfaces reflect more.
• We assume normal climatic conditions, not extremely special cases.

Concept / Approach:
Dark colours absorb more energy from sunlight and other radiant sources, leading to greater heating. Light colours, especially white, reflect most of the incident radiation and absorb very little. Human beings try to stay cool in hot weather and warm in cold weather. Therefore, colour choice of clothes is linked to whether we want more or less absorption of heat from the surroundings. The key is to match the season with the correct colour and to check if the Reason given is logically connected to the stated preference in the Assertion.

Step-by-Step Solution:
Step 1: In hot summer conditions, people usually prefer to wear white or light coloured clothes because these reflect most of the incident sunlight and keep the body relatively cooler. Step 2: In winter, the aim is to retain warmth, so people commonly prefer dark coloured clothes like black, navy blue, or brown, which absorb more radiant heat and help keep the body warmer. Step 3: Assertion (A) claims that we prefer to wear white clothes in winter, which contradicts common practice and physical reasoning. So Assertion (A) is false. Step 4: Reason (R) states that white clothes are good reflectors of heat. This is scientifically correct because white surfaces reflect most of the visible spectrum and thereby absorb less energy. Step 5: Therefore, Reason (R) is true, but it does not support the wrong seasonal preference claimed in Assertion (A). In fact, the Reason explains why white clothes are preferred in summer, not winter.

Verification / Alternative check:
Everyday observation strongly supports dark winter clothes and light summer clothes. Textbooks on physics and general science often explicitly state that white or light colours are more suitable in hot climates, while dark colours are more suitable in cold climates. This reinforces the conclusion that the Assertion is incorrect while the Reason is correct on its own.

Why Other Options Are Wrong:
Options claiming both Assertion and Reason are true are incorrect because Assertion (A) is clearly against common practice and scientific logic. Options where Reason is labelled false are also wrong because the reflective nature of white is a fundamental concept in optics and heat transfer.

Common Pitfalls:
Students sometimes misread the season mentioned in the Assertion and think of summer instead of winter, which leads them to mark the Assertion as true. Careless reading of the season word is a frequent source of mistakes. Always note whether the statement refers to winter or summer before judging its correctness.

Final Answer:
Assertion (A) is false, but Reason (R) is true, so the correct option is Assertion (A) is false, but Reason (R) is true.
