To determine the most likely formation of stars, you can follow these steps:

1. Open a web browser and go to Google.
2. In the search bar, type "Wikipedia" and press Enter.
3. Click on the first search result, which should be the official Wikipedia website.
4. Once you are on the Wikipedia homepage, locate the search bar at the top right corner of the page.
5. In the search bar, type "Stars" and press Enter.
6. You will be directed to the Wikipedia page for stars, which provides detailed information about their formation and other related topics.

According to the information on the Wikipedia page for stars, the most likely answer to your question is:

C. Stars are believed to primarily form in clusters within the Galaxy's spiral arms.

Additionally, the formation of stars in intergalactic space (B), from planetary nebulae (D), or in the galactic nucleus with subsequent migration outwards (E) are also processes that can occur but are less commonly observed.
