C Correct answer
Explanation

When red light falls on objects, the color we see depends on what light each object absorbs or reflects. A green leaf appears green because it absorbs red light and reflects green. Therefore, under red light, the green leaf absorbs all the red and appears black. A red flower reflects red light, so it continues to appear red under red light.
