True or False: When the robot reaches a function call in the program, it runs the code in the body of the function.

The statement is true because when a robot encounters a function call in a program, it executes the code contained within that function. This behavior is a fundamental concept in programming where functions serve as reusable code blocks designed to perform specific tasks.

When a function is called, the program control transfers to the function's body, executing its instructions until it reaches the end or encounters a return statement. Afterward, the control returns to the point in the program where the function was called, continuing from there. This mechanism fosters modularity and organization in code, allowing for easier maintenance and updates.

In contrast, some of the other choices focus on specific conditions that need to be met for a function to execute. While it’s true that a function must be defined in the program for it to be invoked, the question emphasizes the action when a call is made, which directly relates to the execution of the function's body regardless of other conditions unless specified.
