Question 1024 Rules of the Road

The correct answer is D) In distress. The code flag "LIMA" below a red ball indicates that the vessel is in distress and requires assistance. This is a well-established signal in both international and inland navigation rules, used to communicate a vessel's state of emergency to other vessels in the area. The other answer choices are incorrect because they do not match the meaning of the visual signal displayed. Trolling (A), being aground (B), and preparing to receive aircraft (C) are not situations where a vessel would display the "LIMA" flag with a red ball.
