Answer:
B. It targets the quadriceps and hips
Explanation:
While doing a hip flexor stretch on your side you need to lay on your side on the floor, bend your arm to hold your head up while stretching as far as you can. You then need to keep your waist straight and with your other hand grab your top foot's ankle and pull it towards your back. This excercise will stretch both your quadriceps and hips. Once done flip to your other side and repeat the exercise with your other arm and foot.
