Summer Solstice Declination

Explanation:
Declination is the angular distance of the Sun north or south of the celestial equator. At the summer solstice in the Northern Hemisphere, the Sun reaches its farthest north, which is about 23°27' from the celestial equator. That places the Sun over the Tropic of Cancer, hence 23°27' N is the correct value. Why the others don’t fit: 23°27' S would be the southern counterpart, not the Northern Hemisphere solstice. 0° would be the equinox, when the Sun is on the celestial equator. 90° N would be the pole and is not a Sun declination at any time in the year.
