Answer is Wrong!
Answer is Right!
The correct answer is A. accelerate.

not mean to increase speed.- Check means to examine something carefully.
- Control means to have power over something.
- Slacken means to make something less tight or firm.
- Supervise means to watch over someone or something to make sure that they are doing their job properly.
