Final answer:
The dorsal interossei muscles abduct the toes and the plantar interossei adduct the toes, corresponding with the muscle groups' functions in the foot.
Step-by-step explanation:
The dorsal interossei muscles are involved in abducting the toes, which means they move the toes away from the midline of the body. On the other hand, the plantar interossei are responsible for adducting the toes, drawing them towards the body's midline. Therefore, the correct answer to the question is: The dorsal interossei abduct the toes, while the plantar interossei adduct the toes. This aligns with our knowledge about the muscles of the foot where the dorsal side generally works for extension and abduction, and the plantar side for flexion and adduction.
