A position on the Earth has a longitude of 74°10'E. Its celestial counterpart would have a __________.

Correct Answer: Option A — GHA of 285°50'

Greenwich Hour Angle of a celestial body's counterpart corresponds directly to terrestrial longitude when aligned on the Prime Meridian. For 74°10'E longitude, subtracting from 360° gives a GHA of 285°50', following standard celestial conversion formulas found in Bowditch.
