Answer:
- A biography.
Step-by-step explanation:
The classification of a source as primary or secondary depending on the level of significance. Primary sources are those written by witnesses, or from a person's personal account or any direct access to the event(s). On the other hand, a secondary source is when the event is told by someone other than the witness, or retold, making it a second-hand narration or source.
Among the given options, a biography is a secondary source. This is because a biography is written by a person about another person's life. The accounts are provided from the eyes of the narrator and not the person who is the subject of that text. This accounts for second-hand information, making it a secondary source.
Thus, the correct answer is a biography.
