Answer: smokes

Explanation: “When a sentence indicates an action, habitual activity, or universal truth without specifying a particular time, and includes words such as always, often, usually, hardly, seldom, generally, normally, sometimes, occasionally, at times, daily, regularly, frequently, every morning/day/week/month/year/time, on holidays, on (Fridays/Sundays), etc., it will be in the Present Indefinite Tense.”

“Since the word ‘seldom’ is present in the above sentence, the verb will be in the Present Indefinite Tense. The subject ‘the man’ is in the third person singular number, so ‘s’ will be added to the verb. The correct answer will be ‘smokes’.”
