According to E. Gilkman, stars are born in what kind of grouping?

• A. Litters
• B. Clusters
• C. Individually
• D. Galaxies

Answer: (A)

Stars typically form in clusters within giant molecular clouds. Gravity pulls gas and dust together, and regions within the cloud collapse in a coordinated way, fragmentation creating many protostars that share the same birth material and age. This creates a young stellar group that we call a cluster (or an embedded cluster/association while still enshrouded by gas). Observations of star-forming regions, like Orion, show numerous young stars forming in close proximity, supporting the idea that stars are born in groups rather than in isolation. While some stars may drift away from their birth cluster over time, the common formation pathway is in a clustered environment, not individually or in galaxies.
