Detailed Solution

Concept- The above problem can be handled by applying the fundamentals of the phenomenon involved in light ray analysis. This contains concepts such as dispersion, brightness, and luminosity, as well as their various applications. Furthermore, non-luminous objects are those that never have the ability to emit light energy. When light bounces back after falling on them, anything is possible.
Non-luminous objects never have the ability to emit light, hence option (A) is incorrect under the given scenario.
Dispersion of light rays after falling on non-luminous objects, on the other hand, is an incorrect condition because dispersion effects do not apply to non-luminous objects.
However, when light rays fall on some non-luminous things, these non-luminous objects tend to reflect the eye lens of human eyes and can observe the light rays that fall on them and this reflected light. This turns out to be a suitable condition.
As a result, non-luminous objects are visible to the eye because they reflect the light that falls on them, and option (2) is accurate.
Hence, the correct answer is option 2.
