AI Explanation
The correct answer is D) leave the lock.
When you hear one short blast of the whistle from the lock, this indicates that the lock is ready for you to depart. With the lower gates open, it is safe for you to exit the lock and continue your downbound transit on the Ohio River. There is no need to hold up, tie off, or wait for any other traffic, as the lock has completed its operation and is signaling for you to proceed.
The other answer choices are incorrect because: A) you do not need to wait for another tow to enter the adjacent lock, B) there is no indication of a gate malfunction, and C) you should not need to tie off to the guide wall when the lock is ready for you to depart.
