What process occurs when axons attempt to form connections to a grafted limb in a salamander?
A) Axons connect randomly, but only muscles "tuned" to the right message respond.
B) Axons connect randomly and muscles learn to coordinate through experience.
C) Axons find their way to corresponding muscles in the new leg.
D) A lack of nerve growth fiber leads to the degeneration of the new leg.

During regeneration in salamanders, axons find their way to the corresponding muscles in the new limb. This process is guided by specific signaling molecules and gradients that help the axons navigate to the correct destination. Once the axons have formed connections with the muscles, they can send signals to control their movement. This process is essential for the restoration of limb function after injury or amputation. Option A and B are not correct as the axons don't connect randomly, they are guided by signaling molecules. Option D is also not correct as a lack of nerve growth fiber would prevent axons from reaching the muscles, not cause the degeneration of the limb.
