Read the given sentence and choose the correct modal auxiliaries to fill in the blanks.
_____ you come with me to the tailor?

The correct answer is: Will

Here, options a and c both pose the question of whether or not something is supposed to be done, in this particular case, whether or not going to the tailor is okay. These options do not express the possibility of choice and hence they are inappropriate.
Thus option b is the correct answer, as it gives a choice to the person being asked instead of asking the person what's supposed to be done.
