It is an Interjection. So the correct answer is C. Interjections are expressions that shows a reaction. For example: “Oh my gosh! I’m getting a new car!” Or “Ugh! I am so mad at her!”
Answer:
She is at recess, the kids pulled her arm hair.
With my school experience I would have to say B, because a transitive verb has to be an action verb and express a doable activity. An example would be: Sylvia KICKED Juan under the table.
In A: it should be "I was" not "I were".
In B: it should be "lately you appear" not "you appears"
in C: this is correct! the subject is in agreement with the verb, and this is the correct answer.
in D: it should be "you are"
