BOTH INTERNATIONAL & INLAND Which vessel must sound her fog signal at intervals not to exceed one minute?

AI Explanation
The correct answer is B) A vessel aground. The reason this is the correct answer is that according to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel that is aground must sound her fog signal at intervals not exceeding one minute. This is specified in Rule 35(d) of the COLREGS and Rule 35(d) of the Inland Navigation Rules. The other answer choices are incorrect because they do not require the vessel to sound a fog signal at intervals of one minute or less. A power-driven vessel underway but not making way (option A), a vessel constrained by draft (option C), and a vessel engaged in fishing and at anchor (option D) have different fog signal requirements under the regulations.
