A 15, 34, 35, 36, 46, 48
B 14, 34, 35, 36, 46, 48
C 16, 27, 32, 35, 36, 48
D 15, 33, 43, 48
AI Explanation

The correct answer is A) 15, 34, 35, 36, 46, 48. To deballast from tank C2SA using starboard ballast pump #2, the following valves need to be opened: - Valve #15 to allow water to flow from tank C2SA - Valves #34, 35, 36 to direct the flow through the starboard ballast system - Valve #46 to allow the water to be discharged overboard - Valve #48 to enable the starboard ballast pump #2 to operate The other answer choices are incorrect because they do not include the complete set of valves necessary to successfully deballast from tank C2SA using the starboard ballast pump #2. This knowledge is essential for passing the US Coast Guard Captain's License Examination on vessel systems and operations.
