Which segment represents a correct replacement for /∗ more code ∗/ for the toString method?
(A) for (int r = 0; r < ROWS; r++) {
for (int c = 0; c < COLS; c++) {
s = s + “|”;
s = s + board[r][c]; s = s + “|\n”;
} }
(B) for (int r = 0; r < ROWS; r++) {
s = s + “|”;
for (int c = 0; c < COLS; c++) {
s = s + board[r][c];
s = s + “|\n”; }
}
(C) for {
(int r = 0; r < ROWS; r++)
s = s + “|”;
for (int c = 0; c < COLS; c++)
s = s + board[r][c]; }
s = s + “|\n”;
(D) for (int r = 0; r < ROWS; r++) s = s + “|”;
for (int c = 0; c < COLS; c++) {
s = s + board[r][c];
s = s + “|\n”; }
(E) for (int r = 0; r < ROWS; r++) {
s = s + “|”;
for (int c = 0; c < COLS; c++)
