What determines the amount of absorption of light striking an object?

The correct answer highlights how the color of an object plays a significant role in light absorption. An object's color affects the wavelengths of light it reflects and absorbs. For instance, a red object absorbs all wavelengths except for red, which is reflected back to the observer. Therefore, the color determines which part of the light spectrum is absorbed and which part is not, ultimately influencing how much light is absorbed by the object.

In contrast, other factors such as the object's texture, material composition, and temperature also influence its interaction with light. Texture can affect how light is scattered instead of being absorbed, while material composition can determine the absorption characteristics on a broader scale, depending on the inherent properties of the material. Temperature can also have an effect, as it can influence an object's physical state and, therefore, its interaction with light. However, the direct determinant of absorption related to the visible spectrum is primarily the object's color.
