Answer:

The correct answer is "The organizers of the event".

Explanation:

The subject is that part of the sentence that agrees in person and number with the verb.

It is usually a person, an animal or a thing who performs this action. There are the following types of subjects in a sentence:

  • Express subject
  • Tacit subject
  • Undetermined subject

In this case the organizers of the event are the ones who were unhappy, that's why they are the subject.
