Why each option

A JWT (JSON Web Token) is an encoded JSON object that is digitally signed to securely exchange information, commonly used to convey authentication and authorization claims between parties.

Aan encrypted JSON token that is used for authentication

While JWTs can be encrypted (JWE), they are fundamentally encoded and signed, not inherently encrypted, and are used for information exchange, not solely authentication.

Ban encrypted JSON token that is used for authorization

JWTs are primarily encoded and signed, not inherently encrypted, and while used for authorization context, their broader purpose is secure information exchange.

Can encoded JSON token that is used to securely exchange informationCorrect

A JWT is an encoded (typically Base64 URL-safe) JSON object containing claims that can be digitally signed for integrity, allowing for the secure exchange of information between parties, often used for authentication and authorization without needing encryption.

Dan encoded JSON token that is used for authentication

JWTs are encoded JSON tokens, but their purpose extends beyond just authentication to include secure information exchange that can facilitate both authentication and authorization.
