An extra piece of information you pass to a function to customize it for a specific need.

• A. Argument
• B. Parameter
• C. Variable
• D. Input

Answer: (B)

The thing that customizes a function when you call it is an argument. When you define a function, you declare parameters—names that stand in for the values the function will use. When you actually call the function, you provide arguments—the real values that fill those parameters and determine how the function behaves. For example, in a function defined as greet(name), name is a parameter. Calling greet('Alice') passes 'Alice' as an argument. Varieties of terms help distinguish roles: parameter is the placeholder inside the function definition, argument is the actual value supplied at call time, while input is a broader, less precise term and a variable is a storage location for data.
