When ambient temperature changes an astrolabe's components, which inaccuracy increases the most significantly?

A)Alignment of altitude scales
B)Concentricity of rotating discs
C)Etching of hour angle lines
D)Straightness of the alidade edge

💡 Explanation

Misalignment of altitude scales increases because differential thermal expansion changes the components' dimensions; therefore readings become skewed, rather than affecting concentricity directly due to averaging during element placement or etching precision.
