The correct response is:
**Its temperature is uniform.**
The Cosmic Microwave Background (CMB) radiation is remarkably uniform in temperature across the sky, with only slight fluctuations (about one part in 100,000). This uniformity supports the idea that it is a remnant of the Big Bang, indicating that the early universe was very hot and dense and has since expanded and cooled, leaving this radiation as a relic of that time.
