Answer: (C) Recombination
Recombination marks the point when the universe had cooled enough for electrons and protons to combine into neutral atoms, allowing photons to travel freely through space without being scattered by charged particles. This event, also known as the "era of recombination," occurred about 380,000 years after the Big Bang.
