Consider the following method

public static int[][] operation(int[][] mat, int[] vec, int c) { int[][] result = new int[mat.length][mat[0].length]; for (int j = 0; j < mat.length; j++) { for (int k = 0; k < mat[j].length; k++) { if (k == c) { result[j][k] = mat[j][k] + vec[j]; } else { result[j][k] = mat[j][k]; } } } return result; }

The following code segment appears in another method in the same class.

int[][] m = {{1, 2, 4, 2}, {3, 3, 5, 1}, {2, 1, 3, 1}, {1, 3, 2, 4}}; int[] v = {1, 2, 3, 4}; int[][] grid = operation(m, v, 2);

Which of the following represents the contents of grid as a result of executing the code segment?

{{2, 3, 5, 3}, {5, 5, 7, 3}, {5, 4, 6, 4}, {5, 7, 6, 8}}

{{1, 2, 4, 2}, {3, 3, 5, 1}, {3, 3, 6, 5}, {1, 3, 2, 4}}

{{1, 3, 4, 2}, {3, 5, 5, 1}, {2, 4, 3, 1}, {1, 7, 2, 4}}

{{1, 2, 4, 2}, {3, 3, 5, 1}, {2, 1, 3, 1}, {1, 3, 2, 4}}

{{1, 2, 5, 2}, {3, 3, 7, 1}, {2, 1, 6, 1}, {1, 3, 6, 4}}
