The fact that this has been posted multiple times defeats its purpose, but i'm pretty sure there is a correct answer on the other post.
Answer:
A.To prove he is right, Goha fakes his death.
Explanation:
The correct way to write the sentence, "To prove he is right, Goha fakes his death." is by adding a comma after the dependent clause "to prove be is right" because it not only separates the dependent and independent clause but also adds a pause.
The other options are wrong because a comma has the function of separating items or ideas in a sentence to enhance understanding.
