• The verbs in a sentence are the action words that describe what the subject is doing. Verbs, which describe what is happening, are the primary component of a sentence or phrase together with nouns. In fact, even the simplest sentences—like Maria's song—have a verb because complete thoughts cannot be adequately expressed without one. Actually, a verb can be used to begin a sentence on its own by implying the subject, which is usually you in examples like "Sing!" and "Drive!"
• Almost always, verbs follow a noun or pronoun. The term "subject" refers to certain nouns and pronouns.

Here, the sentence is given as,

Someone _____(knock) at the door. Please open it.

Here, the correct form of the verb will be,

Someone is knocking at the door. Please open it.

Hence, the correct sentence is, Someone is knocking at the door. Please open it.
