Concept:An object appears to have a certain colour because it reflects that colour of light and absorbs others.
Explanation:A red rose reflects red light waves and absorbs most other colours, including blue light.
Blue light contains no red wavelengths for the red petals to reflect.
When blue light shines on the rose, the petals absorb the blue light instead of reflecting it.
Since no light is reflected from the rose to the observer’s eye, the rose appears dark, almost black.
Black is the appearance of an object that reflects little or no light.
Answer:D. Black
