If red shirt is being wore by my friend, then I am able to detect the shirt's redness because all the other colors of light are absorbed by the shirt. Correct option is option A.
Light is white in color, but it is composed of seven different colors of varying wavelength in the order of VIBGYOR that is violet, indigo, blue, green, yellow, orange, red. When light from any object falls on our eyes, all the colors are absorbed by the objects itself and other colors are reflected back. This reflected color is seen and detected by eye. This is also known as dispersion of light. White light has 3 primary colors that is red, blue and green. If white light is shining on a shirt, then red, green and blue light is shining on the shirt. If the shirt absorbs green and blue light, then only red light will be reflected from the shirt. So, while red, green and blue light shine upon the shirt, only red light will reflect from it. Red light striking our eye always gives the appearance of red, and the shirt will appear yellow.
