Which error increases when astrolabe alidade misaligned beyond manufacturer tolerance?

A)Inaccurate lunar phase predictions result
B)Zenith distance readings become skewed
C)Hour angle calculations drift further
D)Planetary position plotting becomes compressed

💡 Explanation

When the alidade is misaligned, the angular measurements become skewed because the observer is no longer sighting along a true vertical circle, distorting zenith distance measurements. Therefore the zenith distance readings are skewed, rather than affecting lunar, hour angle calculations or planetary plotting which depend on separate components and scales of the astrolabe.
