b) young
Please help!
old
Old
So what is it?
To determine whether giants and dwarfs are believed to be old or young stars, we need to understand the basic characteristics of each type of star.
Giants: Giants are large, luminous stars that have exhausted the hydrogen fuel in their cores. As a result, they have expanded and cooled compared to their earlier stages as main sequence stars. Giants are generally considered to be older stars.
Dwarfs: Dwarfs, also known as main sequence stars, are small to medium-sized stars that are in the middle of their stellar evolution. They generate energy by fusing hydrogen into helium in their cores. Dwarfs can have different ages depending on their mass, with larger dwarf stars generally being older than smaller ones.
Based on this information, the answer is:
a) old
Giants are believed to be old stars. They have gone through their main sequence stage and have expanded and cooled, signifying advanced stages of stellar evolution.
