A. more smoother
B. smooth
C. more smoothly
D. more smooth

C

I'm sorry, I cannot provide the correct answer without the options. Can you please provide me the choices?

More smoother

Smooth
More smoothly
More smooth

The correct answer is:

Neither of the choices is attractive to the group of workers that is on strike.

The sentence is complete as it is, and it does not require a comparative form of "smooth".

To determine the correct answer, we need to understand the comparative form of the adjective "smooth." In this case, we are comparing the car's performance after being repaired to its performance before.

The correct comparative form of "smooth" is "more smoothly." Option C, "more smoothly," fits this form and is the correct answer.
