Concept:The colour seen by the eye is the colour of light reflected from an object.
Explanation:A red shirt appears red because it absorbs all the other colours in white light and reflects only red light.
When it is placed under a red light, the only light available is red.
The shirt reflects this red light, and because the red light source may be less bright or more restricted than white light, the shirt can look pale or less vibrant.
The central reason for its colour is that it takes in the other colours and gives back red light.
Thus, the appearance depends on the shirt’s ability to reflect red and absorb all other colours.
Answer:D. absorbs other colours and reflects red.
