The hamstring group consists of three muscles located at the posterior side of the thigh - the biceps femoris, semitendinosus, and semimembranosus. The main action of these muscles is to flex the leg at the knee joint, which means to bend the knee and bring the heel closer to the buttocks. Therefore, the correct answer is B - flexion of the leg at the knee joint. The other options listed are actions of different muscle groups - A is an action of the quadriceps group, C is an action of the gastrocnemius and soleus muscles, and D is an action of the tibialis posterior muscle.
