In JavaScript, functions are defined using the function keyword followed by the name of the function, a set of parentheses (), and a block of code enclosed in curly braces {}.

Correct Syntax:
function addNumbers(a, b) {
// function body
}
Explanation:
function: Keyword to define a function.
addNumbers: Name of the function.
(a, b): Parameters for the function.
{ ... }: Function body containing the code to be executed.
Incorrect Options:
A. Void addNumbers(a, b): JavaScript does not use void to define functions.
