Choose the correct form of modal auxiliary verb for the given sentence:
I am really quite lost in this maze of lanes. ________ you mind showing me how to get out of here?

Correct option is B

The correct modal auxiliary verb for the given sentence is would.
Reason for the correct answer:
The phrase "Would you mind" is a polite and common way to make a request in English. It is the most appropriate modal for expressing politeness in this context.
Grammatical rule involved: "Would" is used in polite requests and offers. The structure "Would you mind + verb-ing" is standard for polite questions.
Meanings of the other given options:
· Must: आवश्यक – Expresses obligation or necessity, not polite requests.
· Shall: क्या – Formal suggestion, but not suitable for polite requests like this.
· Could: क्या आप – Polite but less formal than "would", often used when asking for permission rather than making requests.
