In English language, a sentence is a group of words or phrases that comprises a subject and predicate, which are typically used by an author or speaker in order to convey a logical information about a subject matter to an audience (readers or listeners).
A verb is one of the parts of speech in English language and it refers to any word that describes an action, occurrence, or a state of existence.
In this context, we can reasonably infer and logically deduce that the most appropriate word to complete the sentence is "are" because it is a linking verb and it connects the subject with objects in plural form.
