Correct Answer & Explanation
Option A
• The adverb of frequency 'seldom' indicates a habitual or regular action (or lack thereof).
• Habitual actions are expressed using the Present Indefinite Tense (Simple Present).
• The verb 'have' in the sense of 'eat' or 'consume' can be used in the simple present for habits.
• For a third-person singular subject ('He'), the verb takes an '-s' ending. Thus, 'has' is the correct form.
