Among the given objects, the largest one is dwarf elliptical, then ultra-compact dwarf and then globular clusters. Thus, option a is correct.
To find the correct answer, we need to know about the galaxies.
Are galaxies bigger than globular clusters?
- Globular clusters are spherical groups of stars that are primarily located in the spiral galaxy' stellar halo.
- There are 150 or so globular clusters in our Milky Way galaxy, some of which house our galaxy's oldest stars.
- Globular clusters are much smaller than galaxies.
- a system of gas and dust, as well as millions or billions of stars, kept together by gravitational attraction is called galaxy.
- Ultracompact dwarfs are more extended and have higher surface brightness than typical dwarf nuclei.
- Dwarf elliptical galaxies are elliptical galaxies that are smaller than ordinary elliptical galaxies. They are quite common in galaxy groups and clusters and are usually companions to other galaxies.
Thus, we can conclude that, option a is correct.
