Color is a result of the absorption and reflection of light. A shirt appears a color because it reflects that color of light. A shirt appears black when it absorbs all wavelengths of light.

A white object appears white because it reflects all visible wavelengths of light to your eyes. Therefore, the correct choice is “All the light is reflected, so the shirt appears white.” Absorbing sunlight would make the shirt appear dark, not white.
