Concept:A negative sentence contains a word like "not" or "never" to express a denial or opposite idea.
Explanation:Check each option for a negative word.
Option A: "I come from a rich family." – No negative word.
Option B: "You can do all this in no time" – The phrase "in no time" means quickly, but it is not a negative sentence structure; it does not have a negated verb.
Option C: "He does not listen to me" – Contains "not" after "does". This is a clear negative sentence.
Option D: "They are very gentle people." – No negative word.
Only option C uses "not" to negate the action.
Answer:C. He does not listen to me
