Final answer:
The anterior compartment of the leg, featuring muscles like the tibialis anterior and the extensor digitorum longus, is responsible for dorsiflexing the foot and extending the toes. Thus, the option b is the correct answer.
Step-by-step explanation:
The muscles in the anterior compartment of the leg are primarily responsible for dorsiflexion of the foot and extension of the toes. This compartment includes the tibialis anterior, which helps to raise the sole of the foot off the ground; the extensor hallucis longus, which extends the big toe; and the extensor digitorum longus and the fibularis tertius, both involved in extending the other toes. The contraction of these muscles results in lifting the front part of the foot, a movement known as dorsiflexion.
