The correct answer is option C) Documents.

Explanation:
- Life is related to Autobiography in the same way as Witness is related to Documents.
- An autobiography is a written account of a person's life written by themselves, where they document their experiences, memories, and events.
- Similarly, a witness is someone who provides firsthand knowledge or evidence of an event or situation. They can document their observations and experiences in the form of written documents or testimonies.
- Therefore, just as an autobiography is a written document that tells the story of a person's life, witness statements or testimonies are documented accounts of what someone has seen or experienced.
- Hence, the relationship between life and autobiography is the same as the relationship between witness and documents.
- The other options, a) Papers, b) Truth, and d) Acceptance, do not accurately represent the relationship between witness and documents.
- While papers may refer to the physical material on which information is written, it does not necessarily imply a connection with witness or autobiography.
- Truth is a concept that can be related to both witness and autobiography, but it does not specifically represent the relationship between them.
- Acceptance does not have a direct connection with witness or documents. It is more related to the acceptance of a particular situation or idea.
- Therefore, the correct answer is option C) Documents as it accurately represents the relationship between witness and the written accounts or testimonies provided by them.
