On 3 February your 0451 zone time DR position is LAT 24°15.0' S, LONG 124°24.0' W. Considering their magnitude, azimuth and altitude, which group includes the three bodies best suited for a fix at star time?

Correct Answer: Option C — Alphard, Denebola, Acrux

Optimal star identification for a fix requires bodies distributed across the horizon with altitudes between 20° and 70°. Alphard, Denebola, and Acrux provide the necessary azimuth separation and magnitude for the observer's position in the Southern Hemisphere at the specified time.
