The correct answer is: has not yet arrived.
The verb “to arrive” is a transitive verb, which means that it takes a direct object. In this case, the direct object is “some of the luggage”. Transitive verbs are conjugated in the third person singular with the present tense form “has”.
The other options are incorrect because they are not conjugated correctly for the third person singular present tense. Option B, “have”, is the plural form of “has”. Option C, “is”, is the singular form of the verb “to be”, which is not a transitive verb. Option D, “are”, is the plural form of “is”.
Here is a breakdown of the verb tenses in the sentence:
- “Some of the luggage” is the subject of the sentence. It is in the plural form because it refers to more than one thing.
- “Has not yet arrived” is the verb phrase. It is in the third person singular present tense because the subject is “some of the luggage”.
The verb tense in this sentence is important because it tells us when the action of “arriving” is happening. In this case, the action is happening in the present tense, which means that it is happening right now.
