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
The light is transmitted through the shirt, so no color appears.
B
The shirt absorbs the sunlight, so it appears white.
C
All the light is reflected, so the shirt appears white.
D
The sunlight refracts when it hits the shirt, so the shirt appears white.

The appearance of color is a result of the absorption and reflection of certain wavelengths of light. A shirt appears a certain color because it reflects that color of light. On the other hand, a shirt appears black when it absorbs all wavelengths of light and white when it reflects all wavelengths of light.

A
The temperature of the shirt will depend on how much sunlight is diffracted around the shirt.
B
The temperature of the shirt will not change because the sunlight is transmitted through the shirt to the body.
C
The temperature of the shirt will decrease because most of the light is reflected off of the shirt.
D
The temperature of the shirt will increase because all wavelengths of light are absorbed by the shirt.
