Explanation:

A verb is one of the parts of speech in English language. Verbs can be defined as any word that describes an action, occurrence, or state of existence. Some examples of verb are dance, sing, walk, play, run, sit, etc.

In English language, a subject can be defined as the person, thing, idea or place that performs an action.

A subject-verb agreement refers to the situation in which there is an agreement between a subject and a verb in terms of number.

This ultimately implies that, if a subject is singular, its verb should also be singular and if the subject is plural, the verb must be plural.

Hence, the correct subject-verb agreement would be to change the "increase" to "increases" creating an agreement between the subject and the verb.

The Doppler effect results from the fact that as a moving object approaches an observer, the apparent frequency of its sound waves increases.
