Which set of muscles will the soccer player use to straighten his right leg to kick the ball

Quadriceps should be the right answer 

The tarsals, metatarsals and phalanges of your foot provide the contact surface that strikes the ball. The tibia and tarsals form your ankle joint, which must stay slightly flexed but rigid when you kick so that no power is lost. Your knee joint, consisting of the tibia and femur, extends as your thigh muscles contract and your hip, which is made up of your femur and ilium, swings forward in a movement called hip flexion.
