thank you Ms Sue
You're welcome R S.
The correct question form is "How does your son study?"
Explanation: When asking questions using the verb "do" in the present tense, the auxiliary verb "does" is used with the third-person singular subject (he, she, it, or a singular noun). In this case, the subject is "your son," which is a singular noun, so we use the auxiliary verb "does." Therefore, the correct form is "How does your son study?"
