Which term describes a named block of code that can be invoked to perform a task?

• A. Module
• B. Data
• C. Input
• D. Function

Answer: (D)

A function is a named block of code you can call to perform a task. It bundles the steps needed for a specific job, and you invoke it by its name (often with arguments) to run those steps and possibly get a result. This makes code reusable and organized because you define the logic once and reuse it wherever needed. A module is a larger container that groups related code and data, not a single task you call. Data refers to values stored or processed, while input is the data you feed into a program or function. So the term that fits the description is a function.
