Which language is the core for APIs and communication in MySQL?

This question is asking about the main language used by MySQL to communicate with other programs and services. Think of it like the language a computer uses to talk to other computers.

Out of the options given, C is the language most commonly used by MySQL for its core functions. It's like the foundation that everything else is built upon.
