A. summer and winter solstices
B. autumnal and vernal equinox
C. north celestial pole and south celestial pole
D. None of the above
✅ The correct answer is option A.
For observers in the northern hemisphere, the farthest northern point above the celestial equator is the summer solstice, and the farthest southern point is the winter solstice. The word “solstice” means “sun standing still” because the Sun stops moving northward or southward at those points on the ecliptic.
