Number agreement on the ACT refers to the concept that items in a sentence need to match each other in number. Singular items need to be referred to as singular items, and plural items need to be referred to as plural items. This shows up mainly in two forms: Subject-Verb Agreement, and Pronoun Reference.

B is the error.
In this sentence, the verb “have” should modify the noun “director”. Because “director” is singular, the verb should be in its singular form “has”. There is no other error in this sentence. A is idiomatically correct and used appropriately to mean the actors put in long hours each day (“everyday” means ordinary or commonplace). C is in an appropriate tense that matches “noticed”. D is the correct pronoun to use to refer to “actors”.
