Fill in the blank with the most appropriate word. Who ________ next to you now? A. sits B. is sitting C. sit D. sitting

sits
is sitting
sit
sitting

The correct answer is: B. is sitting

The verb “to sit” can be used in the present tense in three different ways:

  • Simple present: This form is used to talk about habitual actions or things that are always true. For example, “I sit in the front row of class.”
  • Present progressive: This form is used to talk about actions that are happening right now. For example, “I am sitting in the front row of class.”
  • Present perfect continuous: This form is used to talk about actions that have been happening for a period of time and are still happening now. For example, “I have been sitting in the front row of class for the past hour.”

In the sentence “Who is sitting next to you now?”, we are asking about an action that is happening right now. Therefore, the correct verb form is the present progressive, “is sitting”.

The other options are incorrect because they are not in the present progressive tense. Option A, “sits”, is in the simple present tense. Option C, “sit”, is the infinitive form of the verb. Option D, “sitting”, is the present participle form of the verb.

I hope this explanation is helpful!
