Answer 2

observes

Each of the girls observes all the regulations.

• All the sentences need to adhere to the subject-verb agreement given some exceptions.

• The Subject-Verb agreement is the need for the subject and the verb in a sentence to agree with each other in order for a sentence to make sense.

• Subjects and verbs must be in a way that they agree in number.
• This is the only rule that forms the basis of this concept.
• Only the subject affects the verb and nothing else matters to make the sentence correct.
• Clauses and  phrases that come in between the subject and verb are do not affect their agreement.
• In this case, as the subject is 'each of the girls'  is a singular subject and should have a singular verb associated with it which is 'observes'.
