The correct answer is 'do you usually have'.

*Key Points

• The sentence asks about a habitual action, and the present simple tense is used to describe habits or repeated actions.
• The correct structure for questions in the present simple tense is "do/does + subject + base verb."
• Option 1 ("are you usually having") is incorrect because the present continuous tense ("are having") is not used for habitual actions.
• Option 3 ("have you usually") and Option 4 ("do usually you have") are grammatically incorrect due to word order issues.

Therefore, the correct answer is Option 2.
