Which sentence is given as an exponent illustrating a polite request?

• A. Could you make me a cup of tea, please?
• B. I like apples
• C. Sea air
• D. Baked beans

Answer: (A)

Polite requests in English are typically formed with a modal verb plus a request verb, often ending with please. The sentence “Could you make me a cup of tea, please?” uses could to soften the request and direct it to the other person, making it clearly a question about performing an action rather than a statement or command. The addition of please further signals politeness. This combination—could you + [do something] + please—is a textbook example of a polite request.

The other options don’t fit because they’re not requests. One is a simple statement about liking something, and the others are noun phrases that don’t convey any action being asked for.
