Option B is correct as data is typically encoded in lightweight formats like JSON or XML. Option D is correct because REST APIs support multiple authentication methods to secure communications. Option C is incorrect because REST APIs are stateless by design, meaning that each request is independent. Option E is incorrect because REST does not require SOAP; in fact, SOAP is a separate protocol.
