A. B. C. D.

C.

JavaScript Object Notation (JSON) and Extensible Markup Language (XML) are the most commonly used data formats for the Representational State Transfer (REST) API and are typically implemented with caching for increased scalability and performance.

Extensible Markup Language (XML) and Security Assertion Markup Language (SAML) are both standards for exchanging encoded data between two parties, with XML being for more general use and SAML focused on authentication and authorization data.

HTML is used for authoring web pages for consumption by web browsers.

REST API (Representational State Transfer Application Programming Interface) is a popular architecture used for building web services. It allows different systems to communicate with each other over HTTP using various data formats.

The two most commonly used data formats for communication and exchange over REST API are XML and JSON.

XML (Extensible Markup Language) is a flexible and widely used data format for exchanging structured data between different systems. It uses tags to define elements and attributes to provide additional information about those elements. XML is widely used in enterprise applications, as well as in the publishing and finance industries.

JSON (JavaScript Object Notation) is a lightweight and easy-to-use data format for exchanging structured data. It is based on a subset of the JavaScript programming language, and its syntax is simpler and more concise than that of XML. JSON is widely used in web applications and mobile apps because it is easy to parse and can be used with any programming language.

SAML (Security Assertion Markup Language) and HTML (Hypertext Markup Language) are not typically used as data formats for communication and exchange over REST API. SAML is used for exchanging authentication and authorization data between different systems, while HTML is used for displaying web content in a browser.

Therefore, the correct answer to this question is C. XML and JSON are the most commonly used data formats for communications and exchange over REST API.
