BOTH INTERNATIONAL & INLAND Which is TRUE for a towing light?

A flashes at regular intervals of 50-70 flashes per minute
B shows an unbroken light over an arc of the horizon of not less than 180° nor more than 225°
C is yellow in color
D All of the above
AI Explanation

The correct answer is C) is yellow in color. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a towing light must be yellow in color. This is to distinguish it from the white masthead lights and stern lights used on other vessels. The other answer choices are not correct - a towing light does not flash at a specific rate, and it shows an arc of light between 112.5 and 135 degrees, not 180-225 degrees.
