Hint: White light is the combination of all colored lights. When white light is projected on a red flower, red color is reflected because the flower absorbs all other light except red and reflects the red light. Use the similar idea when a green light is projected on a red flower. It absorbs all other light and reflects only red light, if it is present.

Complete answer:
When a red flower is exposed to a green light, the flower absorbs all the colors, if there are any, and reflects the red color. As the green color is monochromatic and it is not a combination of different colors, it absorbs the green color and nothing will be reflected. Therefore, the color of the red flower will be black because there’s no other light to get reflected.

So, the correct answer is “Option C”.

Additional Information:
The process through which light rays falling on the surface of an object are sent back is called reflection. Thus, when light falls on the surface of any object, it sends back the light. The objects having shiny or polished surfaces reflect more light compared to the objects having dull or unpolished surfaces. Reflection occurs when the light wave encounters a surface or other boundary that does not absorb energy of light radiation and bounces the eaves away from the surface.

Note:
When we project white light on any object, the object reflects one color and absorbs all other colors. In the above case, there’s only one color projected and no other color is present to get reflected by the flower. Therefore, it reflects no color, which results in a black color.
