The answer is B: Calf stretch this is why...
It is not bicep stretch because your bicep is in your arm and you don't use your arm to walk.
It isnt your shoulder stretch because that is on your back and is responsible for the operation of your neck arms and back.
It could be your abdominal since you use them every time you do anything...but...it isnt targeting the KEY muscle.
The calf muscle is on the lower par of your leg and is connected to your foot and your knee...you use this when you walk.
