Light pollution most severely affects observation of:

1. Solar eclipses
2. Meteors during daytime
3. Faint galaxies and nebulae
4. Moon phases

Correct answer: Faint galaxies and nebulae

Solution

Light pollution brightens the night sky and reduces contrast, making faint celestial objects difficult to observe. Distant galaxies and nebulae are especially affected because they emit very little light. Bright objects like the Moon are much less affected.
