Final answer:
Globular clusters in our Galaxy typically contain hundreds of thousands of stars; the largest, Omega Centauri, has b. several million stars and they are not confined to the central disk but form a halo around the Galaxy.
Step-by-step explanation:
The globular clusters in our Galaxy contain typically hundreds of thousands of stars, and they form a system of clusters in a spherical halo surrounding the center of our Galaxy.
The largest and most massive globular cluster in our own Galaxy, Omega Centauri, contains several million stars.
These clusters are among the oldest parts of the Milky Way Galaxy, with some located at distances of up to 60,000 light-years or more from the main disk.
Therefore, the correct answer to the question "The globular clusters of our galaxy" is b. contain around a million stars each.
