Understanding the Correct Sentence
The correct choice in this case is option B: "He doesn’t know the answer." Let’s break down why this is the right option and analyze the incorrect ones.
1. Subject-Verb Agreement
- He doesn’t know:
- "Doesn’t" is the contraction of "does not," which is appropriate for singular subjects like "he."
- "Know" is the base form of the verb, matching correctly with the auxiliary "does."
2. Incorrect Options Explained
- a) He don’t know the answer.
- "Don’t" is the contraction for "do not," used with plural subjects (e.g., I, you, they). It is incorrect with the singular subject "he."
- c) He doesn’t knows the answer.
- This sentence misuses "knows." The verb should remain in its base form "know" when paired with "doesn't."
- d) He don’t knows the answer.
- This option is incorrect for the same reasons as options a and c. Both "don’t" and "knows" are improperly used.
3. Conclusion
- The sentence "He doesn’t know the answer" is grammatically correct because it uses the proper contraction and verb form for a singular subject.
- Mastering subject-verb agreement and the correct use of contractions is essential for effective communication in English.
