The correct term for a function that appears inside another function is a Nested function.

Explanation:

In programming and mathematics, a nested function (also known as an inner function) refers to a function defined within another function. This structure allows the inner function to access variables and parameters of the outer function, facilitating organized and modular code. For example, in Python, you can declare a function inside another function to achieve this behavior. Nested functions are particularly useful in encapsulating logic and avoiding variable naming conflicts. They can also help improve the readability of your code by encapsulating specific functionality within a broader context.

Thus, the most appropriate answer is Nested function.
