Choose the correct expression to complete the sentence:

How _____ your name?

do you pronounce

The correct answer is Option (3) → do you pronounce

Complete sentence: How do you pronounce your name?

This is a question in the present simple tense, and for such questions with "how," "what," "where," etc., we use the auxiliary "do" with the base form of the verb.

Option 1: "is it pronounced": This would be correct in a passive sentence like: "How is it pronounced?" But in the question "How _____ your name?", the subject is "you", so passive voice doesn't fit here.

Option 2: "you pronounce": This is incorrect because it's a statement structure, not a question. It lacks the necessary auxiliary verb ("do") to form a proper interrogative sentence.

Option 4: "to pronounce": This is an infinitive form, and does not fit the question structure.
It could work in a sentence like: "Tell me how to pronounce your name," but not as a direct question.
