To determine the correct answer, we need to analyze the sentence structure and subject-verb agreement.
1. The subject of the sentence is "the groom, together with his parents," which is a compound subject. In this case, we treat the subject as plural because it consists of more than one noun.
2. The verb in question should agree with the plural subject.
Now let's analyze the options:
A:
is greeting
- This option uses the singular verb "is," which does not agree with the plural subject. Therefore, option A is incorrect.
B:
have greeted
- This option uses the plural verb "have," which agrees with the plural subject. However, the sentence is in the present tense, so the past tense "have greeted" is not suitable. Therefore, option B is incorrect.
C:
are greeting
- This option uses the plural verb "are," which agrees with the plural subject. The present continuous tense "are greeting" indicates an ongoing action, which is suitable for the context of the sentence. Therefore, option C is the correct answer.
D:
were greeting
- This option uses the past tense verb "were," which is not suitable for the present tense sentence. Therefore, option D is incorrect.
In conclusion, the correct answer is option C: "are greeting." This choice correctly uses the plural verb to agree with the compound subject and maintains the present tense of the sentence.
