A)temperature.
B)mass.
C)age.
D)luminosity.

Question

Quizplus · Accepted Answer

Stars in a given cluster are formed from the same cloud of gas and dust, thus they have the same age. This makes star clusters valuable in studying the evolution of stars, as the differences in the stages of evolution of stars in a cluster can be attributed to differences in their masses. However, stars in a cluster may not have the same temperature or luminosity, as these properties can be affected by factors such as composition and distance from the observer.
