The process of evolution of stars in our universe has been interpreted by:
A) matching theoretical models to the properties of similar stars at different distances from Earth since we are seeing more distant stars at an earlier time, when the light left them.
B) matching theoretical models to the collective properties, such as luminosity, temperature, and size, of millions of stars as we see them.
C) designing theoretical models solely on the basis of the known properties of matter, without reference to observational data on real stars, since we do not have a sufficiently long time base for stellar observations.
D) matching theoretical models to the detailed observation of a few stars as we watch them change in luminosity, temperature, and size during their evolution.

The process of evolution of stars in our universe has been interpreted by matching theoretical models to the collective properties, such as luminosity, temperature, and size, of millions of stars as we see them. This method provides a more comprehensive understanding of stellar evolution by considering a wide range of stars and their characteristics, rather than just a few individual stars. Option A is partially correct, as it also involves matching theoretical models to properties of stars, but it limits the observations to only distant stars. Option C is incorrect since it is not possible to create theoretical models without observational data. Option D only involves a few individual stars, and not a comprehensive study of many stars.
