d. it started as a fixed amount that has been spread out wide across the entirety of the universe.
The cosmic background radiation, also known as the cosmic microwave background (CMB), originated from the hot and dense early universe. It was emitted when the universe was about 380,000 years old and has been expanding and getting weaker as the universe itself expands. As the universe expands, the CMB radiation gets spread out over a larger area, making it weaker compared to its initial intensity.
