Step 1: Understanding the Concept:
This question tests the rules of verb forms after auxiliary verbs (helping verbs) like 'do', 'does', or 'did' in negative sentences and questions.
Step 2: Detailed Explanation:
When forming a negative sentence in the simple past tense, we use the structure: did not + [base form of the verb].
The base form of the verb 'to have' is 'have'.
- 'has' is the third-person singular present form.
- 'had' is the past tense form.
- 'did has' is grammatically incorrect.
The auxiliary verb 'did' already indicates the past tense, so the main verb must be in its base form.
The correct sentence is: "My cycle did not have brakes."
Step 3: Final Answer:
The correct option is (B) because after "did not", the base form of the verb ("have") must be used.
