Answer:
c. aluminum foil
Step-by-step explanation:
Reflection is defined as the returning of light or sound wave from a surface at certain angles. For example: our image in the mirror.
To reflect light, we required a surface with one side completely polished, smooth and pure form so that it reflects maximum light rather than absorbing the light. Aluminum foil will reflect the most light from the given options. Aluminum foil has the purity and surface smoothness that makes it able to reflect maximum light. Any change in the smoothness of the aluminum foil, the reflectivity of light will decrease.
Other option a clear window, a green plastic bottle and a red lunch box will absorb more light rather than refect it.
Hence, the correct option is "c. aluminum foil ".
