A company stores a copy of all e-mails sent or received by the organization and the copies of e-mails are an example of Unstructured Data (Option C).
Unstructured Data collected during business operations or researched is information that does not apply to a pre-defined data model or is not organized in a pre-defined manner. Unstructured information is typically text-heavy, but may contain important data such as dates, numbers, and facts as well. Unstructured simply means that it is datasets (typical large collections of files) that aren’t stored in a structured database format. Unstructured data has an internal structure, but it’s not predefined through data models. It might be human generated, or machine generated in a textual or a non-textual format.
