Which sentence correctly asks about someone's age?

• A. How old you today?
• B. What age are you today?
• C. How you old today?
• D. How old are you today?

Answer: (D)

Asking about someone’s age in English uses a yes/no/wh-question pattern with the verb “to be” and inversion after the question word. For age, the natural, correct form is “How old are you today?” Here, “How old” asks about the degree of age, “are” is the inverted form of “you are,” “you” is the subject, and “today” adds the time context. The other options break the standard word order or omit the auxiliary, which makes them ungrammatical or awkward: for example, “How old you today?” misses the inverted auxiliary, “How you old today?” has the words in the wrong order, and “What age are you today?” uses a less natural phrasing for asking age. This makes “How old are you today?” the best choice.
