Answer:
c) grip the steering wheel firmly
Step-by-step explanation:
A) does not make sense because if you let the steering wheel go, you will loose complete control over the vehicle. DON'T DO THIS!
B) Pumping the brakes immediately is NOT recommended in this situation. Articles show that you should if anything accelerate slightly (if needed) to keep the car's momentum until you have gained enough control of the vehicle to where you are able to pull off to the shoulder.
D) Allow yourself the time to get the car under control before immediately pulling off to the shoulder. Depending on which side the tire blew, the car will naturally steer that direction. Pull the steering wheel the opposite direction the car's tire is pulling.
Hope this helps! Stay safe!
