Which of the following would typically be classified as a function in programming?

The correct choice is "Sum" because it represents a specific operation or action that can be encapsulated within a function in programming. A function is a reusable piece of code designed to perform a particular task, which often takes inputs (parameters) and returns an output. In this case, a function named "Sum" would typically take two or more numbers as inputs and return their total, demonstrating the concept of modular code that can be invoked multiple times throughout a program.

The other choices, while related to programming, do not fit the criteria for being classified as a function in the same way. "While" is a control flow statement used for looping, "Print" refers to an action typically provided by a function to output data, and "Prompt" is often used to request input from the user. These terms represent actions or structures in programming rather than standalone functions meant for specific computations or actions.
