When you pass an array to a method, the method receives ________ .

A copy of the array
A copy of the first element
The reference of the array
The length of the array
Explanation:
When sending an array to a method, the method receives the array's reference.
The array reference is returned when a method returns an array.
Arrays are provided to methods in the same way that regular variables are.
When we send an array as a parameter to a method, we are actually passing the memory location of the array (reference).
As a result, any modifications made to this array in the function will have an impact on the array.
