a galaxy is likely to be a collection of which of the following?
universe and interstellar matter
stars and interstellar matter
one star with planets around it
stars and clusters

Explanation:

A galaxy is a large - scale structure in the universe. It is composed of a vast number of stars. Interstellar matter (gas, dust, etc.) is also present within a galaxy. The universe is a much larger concept that contains all galaxies. A single star with planets around it is a planetary system. Clusters are part of a galaxy's structure but not the main components along with stars. So, a galaxy is a collection of stars and interstellar matter.

Answer:

Stars and interstellar matter
