- Step 1: Identify grammatical requirements. The sentence requires correct subject-verb agreement, proper use of articles, and consistent structure. The subject "He" is third-person singular, and the verb should be in the present tense for a general statement.
- Step 2: Analyze each option for errors.
- Option (1): "He have two cats and a dog." Uses "have," which is incorrect for third-person singular; it should be "has." This makes option (1) incorrect.
- Option (2): "He has two cats and a dog." Uses "has," correct for third-person singular, and includes the article "a" before "dog," following standard grammar rules. This appears correct.
- Option (3): "He having two cats and a dog." Uses "having," a gerund form, which is incorrect as the main verb; a proper verb form like "has" is needed.
- Option (4): "He have two cats and dog." Uses incorrect "have" for "he" and omits the article "a" before "dog," violating article usage rules.
- Step 3: Confirm structure. Option (2) follows a clear subject-verb-object structure: "He" (subject), "has" (verb), "two cats and a dog" (objects), with proper articles ("a" before "dog").
- Step 4: Verify correctness. Option (2) adheres to subject-verb agreement, uses the correct present tense verb, and includes necessary articles, making it grammatically sound.
- Step 5: Final conclusion. Option (2) He has two cats and a dog is the only grammatically correct sentence.
