The sentence that accurately describes star clusters is "Stars form large groupings."

Explanation: Star clusters are groups of stars that are held together by their mutual gravitational attraction. These clusters can contain hundreds to thousands of stars and come in various shapes and sizes. Stars within a cluster usually form from the same nebula, so they tend to have similar ages and compositions. This is why star clusters are often referred to as "large groupings" of stars.
