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[]) {
D. toUpperCase();
}
}
E. for (int i:arra.length) {
for (String x:arra) {
arra[i].toUpperCase();
}
}
Answer: C
Explanation:

not A: arra.length is 3, but the subarrays have 2, 3 and 4 elements. Index will be out of
bound.
not B: The subarrys are of different lengths. Index will be out of bound.
not D: Compile error.
