The correct answer is A. Elliptical galaxies are observed to be spheroid and to be comprised mostly of old stars.

Explanation:

An elliptical galaxy is a type of galaxy, with an approximately ellipsoidal shape and a smooth, almost featureless image. Unlike spiral galaxies in which there is organization and structure, elliptical galaxies are more evenly distributed among the three dimensions of space, lacking much structure. Their stars have random orbits, in contrast to the planar and organized orbits of spiral galaxies. The vast majority of these galaxies have little gas, little dust and few young stars. More expressly, they look a lot like the nucleus and halo of spiral galaxies.
