An Electronic Plotting Aid (EPA) will drop off a target's vector if more than minutes elapse between each manual plot.
AI Explanation
The correct answer is D) 10 minutes.
According to the U.S. Coast Guard regulations, an Electronic Plotting Aid (EPA) will drop off a target's vector if more than 10 minutes elapse between each manual plot. This is because the EPA needs regular updates from the manual plots to maintain an accurate vector for the target. If the time between plots exceeds 10 minutes, the EPA will consider the vector information too outdated to be reliable, and it will drop the target's vector from the display.
The other answer choices are incorrect because 6 minutes, 2 minutes, and 3 minutes are not the regulatory time limit specified for an EPA to drop a target's vector.
