That's the definition of "white" - that it reflects a large percentage of the incoming light (all colors get reflected by more or less the same percentage).
A sheet of paper appears white because it reflects most of the light that hits it. The material that makes up the paper scatters the light in different directions, giving it a white appearance to our eyes.
A black sheet of paper has the lowest albedo among the options given. Albedo refers to how much light a surface reflects, and black surfaces absorb more light, reflecting less back. The white sheet of paper would have a higher albedo due to its ability to reflect more light.
A combination of red, green, and blue light on a white sheet of paper would create white light. This is because white light is produced when all three primary colors of light are combined in equal intensities.
Any light that does not contain the primary color red will make the sheet of paper look black. (for example green, blue, cyan,... but not yellow, violet,...) This is because the surface of the sheet is such that it absorbs all the colors of white light except red which is reflected and which is why it appears red in white light.
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.

which is a better reflector of light-a black surface or a white surface

A black sheet of paper has the lowest albedo because it absorbs most of the light that hits it, reflecting very little back. Albedo is the measure of how much light is reflected by a surface, with higher albedo indicating more reflection.
The white paper will absorb all other colors then what makes up white. This way it always stays the same.
The surface of a body of water generally has the lowest albedo among the options provided. Albedo measures the reflectivity of a surface, and water can absorb a significant amount of light, especially at certain angles. In contrast, a black sheet of paper has a low albedo but reflects more light than water, while a white sheet of paper and a mirror have high albedos.
it is white sheet
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
they both look white
Try it! For example, take a white sheet of paper out into the sunlight. If you think about it, you might even remember having seen - or not seen - white objects in white light in the past.
