Answer is Right!
Answer is Wrong!
The correct answer is: Either Sana or her friends were present there.
The verb “to be” agrees with its subject in number. In this case, the subject is “either Sana or her friends.” Since “either Sana or her friends” is a plural subject, the verb “to be” must also be plural. Therefore, the correct answer is “were.”
The other options are incorrect because they do not agree with the subject in number. The verb “was” is singular, but the subject is plural. The verb “is” is also singular, but the subject is plural. The option “none” is incorrect because it is not a verb.
Here is a diagram that shows the agreement between the subject and the verb:
Subject | Verb
——- | ——–
Either Sana or her friends | were present there
