Which distress signal is described as 'Orange Background Black Ball and Square'?

• A. Orange Background Black Ball and Square
• B. Red Star Shells (Flares)
• C. Smoke
• D. Waving Arms

Answer: (A)

Distress signaling on the water includes flag signals you can recognize from a distance. An orange background with a black ball and square is the standard daytime distress flag. The bright orange field makes it highly visible, and the fixed black shapes identify it as a call for help to nearby boats and authorities. This is a flag-based signal, distinct from nighttime flares or other daylight cues.

The other options describe different signal types: red star shells are nighttime flares, smoke is a daylight visual signal, and waving arms is a personal, universal distress gesture. So the signal described by the orange background with the black ball and square is the flag-based daytime distress signal.
