BlackTom AI · Accepted Answer

When examining what a function is, we should compare each option to the standard definitions in programming.
Option A: 'is a static group of code that performs a task but can’t return anything.' This describes a procedure that cannot produce a result, effectively limiting usefulness. In many languages, functions or methods can return values, so this statement is too restrictive and inaccurate for the general concept of a function.
Option B: 'stores a value in a named memory location.' This describes a variable or storage location, not a function. While functions may use variables internally, the act of storing a value in memory is not the primary purpose of a function, making this option incorrect.
Option C: 'is a reusable block of code that performs a task and may return an object.' This aligns well with the standard idea of a function: a defined, reusable block that executes a task, and it may return a value (often an object, but not necessarily limited to objects depending on the language). This captures both reusability and the potential to produce a result.
Option D: 'must return an object.' Requiring a function to return an object is overly prescriptive and language-specific; many functions can return primitives, strings, booleans, lists, or nothing at all. Therefore this statement is incorrect as a universal rule.
