Which outcome occurs when calibrating a medieval Islamic astrolabe using Polaris near the celestial pole?

A)Inaccurate timekeeping due to stellar aberration
B)Cumulative error in latitude measurements
C)Parallax error affecting planet altitude
D)Declination shift altering solar alignments

💡 Explanation

When calibrating with Polaris, small observational errors accumulate because Polaris isn't exactly at the celestial pole, causing a consistent offset in the altitude readings and thus latitude. Therefore cumulative latitude errors result, rather than timekeeping errors, parallax issues (more relevant to closer objects), or solsticial alignment variation which stems from ecliptic angle changes.
