Explanation:

In JavaScript, code can be executed in multiple ways, but the most common and structured way is through functions or methods. A function is a reusable block of code that performs a specific task when called.

Example of Calling JavaScript Code Using a Function:

function greet() {

    console.log("Hello, World!");

}

greet();  // Calling the function

Why Not Other Options?

(A) Preprocessor → ❌ Incorrect
JavaScript is an interpreted language, meaning it does not require preprocessing like languages such as C or C++.

(C) RMI (Remote Method Invocation) → ❌ Incorrect
RMI is a Java-based technology used for remote procedure calls, not for JavaScript execution.

(D) Triggering Event → ❌ Partially Correct
Events like onClick, onLoad, etc., can execute JavaScript, but they usually call functions to perform the actual logic.

Final Answer:

✅ (B) Function/Method
