Answer 1

Have you got a light ? - Sorry, I do not smoke - Present Simple

Answer 2

Have you got a light ? - Sorry, I do not smoke. (Present Simple)

Answer 3

The correct sentence should be: "Sorry, I don't smoke."

In this case, you're using the present simple tense to indicate a habitual action or a general state. "I don't smoke" means that it's not something the person does regularly or as a habit.
