Correct Answer :

D. All of the mentioned above


Unstructured data is primarily derived from social media platforms such as Twitter, Facebook, and the Internet. In the context of data storage, unstructured data refers to information that has not been organized according to a pre-determined data model or schema, and hence cannot be stored in a standard relational database management system (RDBMS). Text and multimedia are two types of unstructured content that are frequently encountered. Many business documents, as well as email messages, videos, images, webpages, and audio files, are unstructured in their content.
