Final Answer:
The "big bang" that produced the universe is thought to have occurred 12 to 14 billion years ago (Option B).
Step-by-step explanation:
Scientific consensus places the occurrence of the "big bang" around 12 to 14 billion years ago. This event marked the beginning of the universe, with an extremely rapid expansion of matter and energy. The estimate is based on observations of cosmic microwave background radiation, the rate of cosmic expansion, and the age of the oldest celestial objects. Option B, 12 to 14 billion years ago, aligns with this widely accepted scientific understanding of the universe's origin.
In summary, the most accurate approximation for the timing of the "big bang" is 12 to 14 billion years ago.
Option B is answer.
