Option d. Ionosphere is correct Answer.
Radio waves are primarily reflected by the ionosphere. The ionosphere is a layer of Earth's upper atmosphere, which is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth.
