Show answer & explanation
Correct answer: D
A formal parameter (often just called a "parameter") is the placeholder variable defined in the function's signature or declaration. It establishes the name and data type of the input the function expects to receive. When the function is actually called, these formal parameters are initialized with the real values (called actual parameters or arguments) passed by the caller.
