Hey there!
A transitive verb is a word that has to be done with something.
For example, "She drank a cup of juice." In the sentence, it says that "she" drank something. The word "drank" is the transitive verb.
Let's see which one of the words is the transitive one:
Snore - This is not a transitive verb because you cannot snore something.
Complain - This is not a transitive verb because you cannot complain something, you can only complain about something.
Remove - This is a transitive verb. This is because you can remove something. For example, you can remove a bandage.
The correct answer is option C. remove.
Hope this helps you.
Have a great day! :)
