Question

Which of the following is a non luminous body?

• A. The Sun
• B. A star
• C. A planet
• D. All of these

Answer 1

The correct option is C A planet

Non luminous bodies are those bodies which do not emit light of their own, but are visible when light falls on those. Planets do not have their own light. They reflect light from the Sun and are thus visible.

Stars and the Sun are luminous objects and they emit light.
