How many of the following languages can interface to bind to the C API of MySQL?

Perl, PHP, Python

This question asks about languages that can "interface" with MySQL's C API. Think of it like this:
* MySQL is like a powerful engine that stores and manages your data. * C API is like a special set of tools and instructions that let you directly control the engine. * Programming Languages (like Perl, PHP, and Python) are how you write instructions to tell the computer what to do. The question wants to know if these programming languages can use those special tools (the C API) to talk to MySQL directly.
The Answer: All three languages (Perl, PHP, and Python) can use the C API to interact with MySQL. Therefore, the correct answer is Option D: 3
