Question

Fill in the blank with the most suitable verb and verb form:
This dog ___ very loudly.

• A. Barks
• B. Bark
• C. Barking
• D. None of these

Answer 1

Answer: (A)

Barks

A word used to describe an action, state, or occurrence, and forming the main part of the predicate of a sentence is a verb.

With a third-person singular noun or pronoun (he, she, it, boat, dog, cat, etc) singular verb is used and singular verbs end with "s" or "es". The "dog" over here is in the third person singular number and it requires a singular verb to be used here. Thus, we will use "Barks" in this case.

Therefore option A is correct.
