Suggested Answer: B 🗳️
JSON-RPC is an RPC protocol built on JSON, as a replacement for

XML-RPC -
or

SOAP -
. It is a simple protocol that defines only a handful of data types and commands. JSON-RPC lets a system send notifications (information to the server that does not require a response) and multiple calls to the server that can be answered out of order. Example of a JSON-RPC 2.0 request and response using positional parameters.
