Explanation:

To determine the number of galaxies in the universe, we refer to scientific estimates. Current astronomical research suggests that the number of galaxies in the observable universe is approximately 200 billion. The other options (12,000, 250, 3 million) are far too low to be consistent with scientific understanding of the universe's scale.

Answer:

The best answer is the option corresponding to "200 billion" (the third option in the list).
