Answer:
The answer is indeed C) His language captures his fear and his panic.
Step-by-step explanation:
In this excerpt, Twain compares himself to a squirrel when he "began to climb the wheel". His movements were probably rapid since he was desperate to get the boat to the port. He also uses the adjective "crazy" to describe his feeling when he realized there were perils accumulating to starboard. He couldn't get to port, he couldn't go to the opposite direction... he was afraid and in panic, not knowing how to escape the dangers surrounding the boat.
