<script>
	var cars = ["Honda","Hyundai","Mahindra"];

	var result = cars.unshift("Toyota", "Tata");

	document.writeln("[", result, "] ", cars);

2. [5]Honda,Hyundai,Mahindra,Toyota,Tata
3. [2] Toyota,Tata
4. [5] Honda,Hyundai,Toyota,Tata,Mahindra

Answer: A) [5] Toyota,Tata,Honda,Hyundai,Mahindra

Explanation:

In the above JavaScript code, we used unshift() method which is used to add one or more elements in the beginning of the given array and returns the updated array. This method changes the length of the original array. Thus, the output would be "[5] Toyota,Tata,Honda,Hyundai,Mahindra".
