On 10 June your 1712 zone time DR position is LAT 25°10.0' S, LONG 06°58.0' E. You are on course 213°T at a speed of 9.0 knots. Considering their magnitude, azimuth, and altitude, which group includes the three stars best suited for a fix at star time?

Correct Answer: Option D — Acrux, Procyon, Arcturus

Selecting stars for a fix requires a balanced distribution of azimuths, typically 120 degrees apart, to ensure a strong geometric intersection. Acrux, Procyon, and Arcturus offer the best combination of brightness and spatial separation for a navigator at the specified southern latitude and time.
