BOTH INTERNATIONAL & INLAND Which vessel would exhibit sidelights when underway and not making way?

A A vessel pushing ahead
B A vessel trawling
C A vessel not under command
D A vessel engaged in dredging
AI Explanation

The correct answer is A) A vessel pushing ahead. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel pushing ahead must exhibit sidelights when underway and not making way. This is because a vessel pushing ahead is considered to be "underway" even if it is not making progress through the water. The other options, such as a vessel trawling, a vessel not under command, or a vessel engaged in dredging, have different lighting requirements that do not involve exhibiting sidelights when underway and not making way.
