Concept:A luminous object gives out its own light, while a non-luminous object can only be seen because it reflects light from another source.
Explanation:The sun produces its own light through nuclear reactions in its core, so it is a self-luminous object.
Stars shine by their own light just like the sun, so they are luminous objects.
A lit candle burns fuel and gives out light and heat, so it is also a luminous object.
The moon, however, does not produce any light at all.
The moon appears bright at night only because it reflects sunlight that falls on it.
If sunlight did not reach the moon, it would be completely dark in the sky.
This shows that the moon is a non-luminous object.
Therefore, the correct choice is the moon.
Answer:B. The moon
