Luminous objects such as flashlights emit light that we can see. How do we see an object that isn't luminous?

A. The object emits light that reaches our eyes.

B. Light reflects off the object and reaches our eyes.

C. Light passes through the object uninterrupted.

D. Light is fully absorbed by the object.

E. We can't see an object that isn't luminous.

The object which are not luminous are observed by the light reflected off the object and reaches our eyes.

Option B

Explanation:

A non-luminous object reflects light from its surface that is incident on it from some other luminous source or body, to be seen by the naked eye as a whole. The light reflected, reaches the observer's eyes and is viewed as a result.

Non-luminous objects never emit their light, rather they are dependent on luminous objects to be seen by the observer. A piece of cloth, moon, earth, wood, plastics, metals, etc. are some fundamental examples of a non-luminous object.

B is the correct answer.
