Explanation
Valid SIP URI formats must conform to RFC 3261 (SIP) or RFC 3986 (URI general syntax). A ('[email protected]') is a valid SIP address-of-record format used in SIP headers. B ('tel:[email protected]') is a valid TEL URI format as defined in RFC 2806/3966, used to represent telephone numbers. D ('sip:[email protected]:5060;user=phone') is a fully qualified SIP URI including scheme, user, host, port, and URI parameter - all valid components. C ('phone:[email protected]') is incorrect because 'phone:' is not a recognized URI scheme in SIP standards. E ('sip:bob.cisco.com') is invalid in this context because it lacks the required user portion and '@' separator, making it ambiguous as a proper SIP URI.
