BOTH INTERNATIONAL & INLAND When may a pilot vessel continue to sound an identity signal in fog?

AI Explanation
The correct answer is C) When at anchor. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a pilot vessel is required to sound an identity signal (such as a whistle or horn) when not on pilotage duty or when at anchor. This helps other vessels identify the pilot vessel's presence, especially in conditions of restricted visibility like fog. Continuing to sound the identity signal when at anchor is the correct action, as it ensures the pilot vessel is properly signaling its location. The other options (A, B, and D) do not represent the proper use of the identity signal as per the navigation rules.
