Question

the process from interstellar cloud collapse to fusion ignition takes around 1 million years. 10 million years. 100 thousand years. 1,000 years.

Explanation:

In astrophysics, the process from inter - stellar cloud collapse to fusion ignition typically takes around 10 million years. This is due to the time required for the cloud to condense under gravity, heat up, and reach the conditions necessary for nuclear fusion to start.
