Answer 1

Hint:Read the given phrase/sentence carefully. Try to make out the meaning of it and find the subject or the predicate or the main object of the sentence.

Complete answer:
We have to fill in the correct answer as to how to ask to use a friend’s phone. There can be more than one answer to this question. Modal Verbs show us the attitude of the speaker to what is being said or done. The term “modal” means expressing mood and mood is a way to express the attitude of the speaker. The sentence requires a modal verb which expresses possibility and politeness in asking permission.
Now, let us examine all the given options to find out the correct option -
Option ‘a’ is May I use your phone? It is a polite manner of speaking and also a logical way of asking for the phone from a friend. This is the correct option for this question.
Option ‘b’ is Could I use your phone? It is also a polite way of asking for the phone from a friend. It is also a correct option for this question.
Option ‘c' is Will I use your phone? This is an illogical phrase as it depicts a future possibility, and cannot be used in the given question.
Option ‘d’ is Shall I use your phone? This is also depicting the future tense. It cannot be the correct answer to this question. Hence, option ‘a’ and ‘b’ are the correct option.

Note:
 See that in such questions, you must have a ratio of politeness in your answer as you are asking for something from someone.
