Given the code fragment:

Which code fragment at line 10 prints Welcome 100?

• A.Option A
• B.Option C
• C.Option B
• D.Option D

Given the code fragment:
public class Test {
static String[][] arr =new String[3][];
private static void doPrint() {
//insert code here
}
public static void main(String[] args) {
String[] class1 = {"A","B","C"};
String[] class2 = {"L","M","N","O"};
String[] class3 = {"I","J"};
arr[0] = class1;
arr[1] = class2;
arr[2] = class3;
Test.doPrint();
}
}
Which code fragment, when inserted at line //insert code here, enables the code to print COJ?

• A.for (int i = 0;i < arr.length-1;i++) {
  int j = arr[i].length-1;
  System.out.print(arr[i][j]);
  i++;
  }
• B.int i = 0;
  for (String[] sub: arr[][]) {
  int j = sub.length;
  System.out.print(arr[i][j]);
  i++;
  }
• C.private static void doPrint() {
  for (int i = 0;i < arr.length;i++) {
  int j = arr[i].length-1;
  System.out.print(arr[i][j]);
  }
  }
• D.int i = 0;
  for (String[] sub: arr) {
  int j = sub.length -1;
  for (String str: sub) {
  System.out.println(str[j]);
  i++;
  }
  }

return 0;
}
}

• A.An exception is through at runtime.
