BOTH INTERNATIONAL & INLAND A vessel 50 meters in length at anchor must sound which fog signal?

A 5-second sounding of a gong every minute
B 5-second ringing of a bell every two minutes
C 5-second sounding of both a bell and gong every two minutes
D 5-second ringing of a bell every minute
AI Explanation

The correct answer is D) 5-second ringing of a bell every minute. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel 50 meters or more in length at anchor must sound a 5-second ringing of a bell every minute. This is specified in Rule 35(a) of both the COLREGS and Inland Navigation Rules. The other options are incorrect because they do not match the specific requirement for a 5-second ringing of a bell every minute for a vessel of this size at anchor, as per the relevant regulations.
