Step 1: Understanding the Concept:
Converting an assertive sentence in the simple present tense with a plural subject (such as "We") into a negative sentence requires using the auxiliary verb "do" followed by "not" and the base form of the main verb.
Detailed Explanation:
Let us analyze the grammatical structure of the given sentence:
- Sentence: "We accept all types of cards."
- Subject: "We" (first-person plural pronoun).
- Verb: "accept" (simple present tense, plural form).
For first-person and plural subjects, the negative structure is:
\[ \text{Subject} + \text{do not (don't)} + \text{Base Verb (V}_1\text{)} + \text{Object} \]
Let us evaluate the options:
- Option (A) incorrectly uses "doesn't", which is only used for third-person singular subjects.
- Option (B) incorrectly combines "have not" with the base verb "accept" instead of the past participle "accepted".
- Option (D) uses the past tense "did not", which changes the tense of the original simple present sentence.
- Option (C) correctly uses "don't accept", maintaining the simple present tense and matching the plural subject "We".
Step 2: Final Answer:
The correct negative sentence is Option (C).
