I shall take revenge . . . . . . . you.

The correct answer is on.

The preposition on is used to indicate the person or thing that is the object of an action. In this case, the action is “taking revenge”, and the object is “you”. Therefore, the correct preposition is “on”.

The other prepositions are not correct because they do not indicate the object of the action. The preposition at is used to indicate a location or direction. The preposition with is used to indicate a tool or instrument. The preposition from is used to indicate a source or origin.

Here are some examples of how the preposition on is used:

• I took revenge on my enemy.
• The government took revenge on the rebels.
• The victim took revenge on the perpetrator.

I hope this helps!
