Answer: A. The true meridians at different places are parallel to each other

Explanation

True meridians converge at the geographic poles and are not strictly parallel. Meridians form intersecting great circles converging toward the northern and southern poles. Assuming meridians are parallel introduces errors over large north-south survey distances. True meridian at any specific location points directly toward the geographic north pole. National mapping agencies base their official coordinate grids on true meridian references. Convergence of meridians is a fundamental principle of geodesy and spherical geometry.

Geodetic surveyors apply convergence corrections when mapping large geographic regions. Ignoring meridian convergence causes boundary misalignments in extensive state grid systems. Accurate geodetic control is vital for national infrastructure and mapping databases. Option B is true because the true meridian at any fixed location remains constant. Option C is true since meridians genuinely converge at both geographic poles. Option D is true because official national maps rely on true meridian control.
