In terms of reflection, how does a white object behave?

A white object behaves by reflecting all colours of light that hit its surface. This phenomenon occurs because the pigments in a white object do not absorb any specific wavelengths of light; instead, they reflect the entire spectrum of visible light. When light, which consists of many colours (red, orange, yellow, green, blue, indigo, violet), strikes a white surface, all of these wavelengths are reflected back to the observer’s eye, which is why we perceive the object as white.

In contrast, other colours will absorb certain wavelengths and reflect others. For instance, a red object primarily reflects red wavelengths while absorbing other colours. Both the options regarding reflection of some colours and absorption of all colours do not accurately describe the behaviour of a white object, as they imply selective reflection or absorption which does not occur with white objects. Similarly, a choice stating that a white object absorbs all colours contradicts the fundamental property of white surfaces, which is to reflect the entire visible spectrum.
