Either of the friends ___ tostay for the night.A. chooseB. chosesC. choosesD. has chose

The correct answer is C. "chooses".

Here's why:

The subject of the sentence is "Either of the friends". In English, when "either" is used as a subject, it is typically followed by a singular verb. Therefore, we need a singular form of the verb "choose".

Option A "choose" is the base form of the verb, which we use for plural subjects (like "they" or "we") or with the pronouns "I" and "you".

Option B "choses" is not a correct form of the verb "choose" in English.

Option C "chooses" is the third person singular form of the verb "choose", which we use with singular subjects (like "he", "she", "it", or "either of the friends" in this case).

Option D "has chose" is incorrect because the correct form should be "has chosen", which is the present perfect tense of the verb "choose". But in this sentence, we need a simple present tense verb.

So, the correct answer is C. "chooses". The correct sentence is: "Either of the friends chooses to stay for the night."
