A sentence has been given with a blank to be filled with an appropriate option. Choose the correct alternative.
The need to take theatre online ________ in global collaborations.

Correct option is B

The correct option to fill in the blank is (b) has resulted.
This sentence is in present perfect tense where the subject is "The need", which is singular.
So, the correct verb form is "has resulted", not "have resulted".
Grammatical rule used:
Present perfect tense = has/have + past participle.
Singular subject takes has, plural subject takes have.
Example: The crisis has resulted in widespread unrest.
Why other options are incorrect:
· (a) result: simple present plural form—doesn't agree with singular subject.
· (c) resulting: verb form inappropriate here; needs auxiliary verb.
· (d) have resulted: plural form—incorrect for singular subject "The need".
Information Booster:
Present perfect tense shows an action that occurred in the past and has relevance to the present.
