BOTH INTERNATIONAL & INLAND Which display indicates a vessel conducting mine clearance operations?

A Two balls in a vertical line at the end of each fore yard
B One diamond near the foremast and one ball at each end of the yardarm
C Three balls in a vertical line
D One ball near the foremast head and one ball at each end of the fore yard
AI Explanation

The correct answer is D) One ball near the foremast head and one ball at each end of the fore yard. This is the correct answer because the International and Inland Navigation Rules specify that a vessel engaged in mine clearance operations shall display the following signals: one ball near the foremast head and one ball at each end of the fore yard. The other answer choices do not correctly represent the display required for a vessel conducting mine clearance operations. A and B describe different signal configurations, while C describes a signal that is not specified for mine clearance operations.
