Answer:
B. reflects red light only. ✅
Step-by-step explanation:
Opaque objects are given a color based on the colors they reflect.
The color of an opaque object depends on the ability of the object to reflect or absorb light of certain colors.
For example:
An object that reflects all the light in the visible spectrum equally well appears white. ⚪
An object that absorbs all the visible light falling on it, regardless of color, appears black. ⚫
An object that reflects light of a single color of the visible spectrum and absorbs light of all other colors appears to have the color of the reflected light.
So, an object that reflects only red light, absorbing all other colors, appears red.
Therefore, the correct answer is, in fact, B. reflects red light only. ✅
