Card 11 / 37: String[][] arra = new String[3][]; arra[0] = new String[]{"rose", "lily"}; arra[1] = new String[]{"apple", "berry","cherry","grapes"}; arra[0] = new String[]{"beans", "carrot","potato"}; // insert code fragment here Which code fragment when inserted at line '// insert code fragment here', enables the code to successfully change arra elements to uppercase?
A) String[][] arra = new String[3][]; arra[0] = new String[]{"rose", "lily"}; arra[1] = new String[]{"apple", "berry","cherry","grapes"}; arra[0] = new String[]{"beans", "carrot","potato"}; for (int i = 0; i < arra.length; i++) { for (int j=0; j < arra[i].length; j++) { arra[i][j] = arra[i][j].toUpperCase(); } }
B) for (int i = 0; i < 3; i++) { for (int j=0; j < 4; j++) { arra[i][j] = arra[i][j].toUpperCase(); } }
C) for (String a[]: arra) { for (String x:a) { x = x.toUpperCase(); } }
D) for (int i:arra.length) { for (String x:arra) { arra[i].toUpperCase(); } }
E) No one
