B)restrains/slows extension of toes two through five at the metatarsophalangeal and proximal interphalangeal joints
C)restrains/slows flexion of toes two through four at the metatarsophalangeal and proximal interphalangeal joints
D)restrains/slows abduction of fingers two through five at the metacarpophalangeal joints

The flexor digitorum brevis is located in the foot, not the hand, and its function includes flexing the toes, particularly toes two through five. Therefore, in an eccentric contraction, where the muscle lengthens under tension, it would help to restrain or slow down the extension of these toes at the metatarsophalangeal and proximal interphalangeal joints.
