What is the result?

This question is wrong. The correct answer is “Compilation fails”

public class Test3 {
public static void doChange(int[] arr) {
for(int pos = 0; pos < arr.length; pos++) {
arr[pos] = arr[pos] + 1;
}
}
public static void main(String[] args) {
int arr[] = {10, 20, 30};
doChange(arr);
for(int x : arr)
System.out.println(x);
doChange(arr[0], arr[1], arr[2]); // does not compile
for(int x : arr)
System.out.println(x);
}
it does not compile, if changed so that it compiles the answer is D
