Step 1: Understanding the Concept:
The question asks for the reasons why clothing is essential for humans. The functions of clothing extend beyond basic physical needs.
Step 2: Detailed Explanation:
Let's analyze the functions listed:
(A) Providing cover for the body: This is a primary function of clothing, offering protection from the elements (sun, rain, wind), insects, and injuries. It also serves the purpose of modesty.
(B) Keeping the body warm: Clothing acts as insulation, trapping a layer of air next to the skin, which helps to retain body heat and maintain a stable body temperature, especially in cold climates.
(C) Social prestige: Throughout history and across cultures, clothing has been used as a means of communication. It can signify a person's status, occupation, wealth, and social prestige. Uniforms, ceremonial robes, and designer labels are all examples of this.
Since clothing serves physical, protective, and social functions, all the given options are correct.
Step 3: Final Answer:
Clothing is essential for providing cover, keeping the body warm, and as a symbol of social prestige.
