Question

Fill in the blank with the most appropriate word.

"Do you want a cigarette?"
"No, thanks. I _____ ."

• A. no smoke
• B. smoke not
• C. am not smoking
• D. don't smoke

Answer 1

Answer: (D)

don't smoke

Singular pronouns should take singular verb forms. In the simple present, most regular verbs use the root form, like with first person singular, "I". The root form of smoke is "smoke'". Its negative is "don't smoke". Hence, Option D is correct. The rest of the options do not adhere to this rule, hence incorrect.
