Answer 1

The correct option is C None of the above.

All the given statements are correct.
Objects like the Sun, which give out or emit light of their own, are known as luminous objects. Others examples include electric bulb, torch, and more. Non-luminous objects do not emit their own light but are visible only when light from a luminous source gets reflected from them.
