Which of the following is NOT a common data format used in Data Science projects?

JSON
XML
CSV
HTML

The correct answer is D. HTML.

HTML is a markup language used to create web pages. It is not a data format, but rather a way to structure and present data. JSON, XML, and CSV are all data formats that are commonly used in Data Science projects.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy to read and write, and is used to transmit data between a server and a client.

XML (Extensible Markup Language) is a markup language that is used to define data structures. It is more complex than JSON, but is more flexible and can be used to represent a wider variety of data.

CSV (Comma-Separated Values) is a text-based data format that is used to store tabular data. It is simple and easy to use, but is not as efficient as JSON or XML.
