A function is executed in a program when **it is called in the main code**.
Here’s a brief explanation for each option you mentioned:
- **When it is written in the code**: This is incorrect. Simply writing a function does not execute it; it must be called to run.
- **When the program starts running**: This is incorrect as well. A program starts by executing the main code or the entry point, but functions are executed only when explicitly called.
- **When it is called in the main code**: This is the correct answer. A function executes when it is invoked or called in the program.
- **Automatically at the end of the program**: This is incorrect. Functions do not automatically execute at the end of a program unless explicitly called.
In summary, functions are executed when they are called during the program's execution.
