BOTH INTERNATIONAL & INLAND Fog bell signals for vessels at anchor or aground shall be sounded at not more than which time interval?

A 15 minutes
B 5 minutes
C 2 minutes
D 1 minutes
AI Explanation

The correct answer is D) 1 minute. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, vessels at anchor or aground are required to sound their fog bell signals at intervals of not more than 1 minute. This is specified in Rule 35(g) of both the COLREGS and the Inland Navigation Rules. The other options are incorrect because they do not match the regulatory requirement of a 1-minute interval for fog bell signals from vessels at anchor or aground.
