A document is a set of ___

8. A document is a set of ___.

1. Key-value pairs
2. Application pairs
3. Activity pair set
4. None of the mentioned above

Answer: A) Key-value pairs

Explanation:

A document is a collection of key-value pairs that are stored together. Documents have a dynamic schema that changes over time. Using a dynamic schema, documents in the same collection do not all need to have the same set of fields or structure, and the same common fields across multiple documents in a collection may contain different types of data.
