In the case where a large number of stars of different masses all form at the same time (e.g.,in a cluster of stars),what does the phrase initial mass function mean?
A) the mass of the largest star in the cluster divided by the mass of the smallest star
B) the mass of the original cloud of gas and dust that collapsed to form the cluster
C) the graph or equation relating the mass of each star to its luminosity
D) the number of stars that form at each mass

The initial mass function refers to the distribution of masses of stars that form in a cluster or in a certain region at the same time. It describes the number of stars that form at different mass ranges, and it can be shown as a histogram or a mathematical equation that characterizes the typical mass range of stars in the population. Options A, B, and C do not accurately capture the meaning of the initial mass function.
