If you are trying to reduce the stress of a project it is best to take a break from the project when you need it then come back to it when your ready so i would say the answer is B.
Under most normal circumstances and as an EMT. You should just turn off power to the fridge using the fuse box. However in this circumstance your best answer is to pull him away using a nonconducting material keeping yourself away from the fridge as much as possible. You would move him a safe distance from the fridge and listen for a pulse, breathing, and just to see if he is conscious. If he is pulseless, Apneic (not breathing), and Unresponsive you start CPR.
I believe it’s D. It’s not A because when you use your muscles you’re getting micro tears that repair and grow.
