Pick the correct option to complete the following sentence :
"All the students and teachers _______ this book."

All students and teachers are a plural subject.

So, the verb must be singular.

So, option A (likes) is wrong.

Additionally, option C (liking) doesn't make sense. This is because the verb is now in continuous form, and for that we need a main verb, for instance, are liking.

Similarly , in option D, "are like" is also incorrect because when "are" is used , we must convert like in participle form (liking).

So, the correct answer is option B (like).
