Java 2D Array Calculation: Understanding the Output (Option C)

This Java code snippet initializes a 2D array 'sum' with 4 rows and 4 columns. The first row and column are set to 1 using two for loops.

The nested for loop starting at line 5 calculates each element's value by adding the element to its left and diagonal left-up. This pattern forms a specific calculation based on the previous values in the array.

Finally, the last for loop starting at line 8 prints the values of the last row of the array, resulting in the output: '2 4 10'.

Therefore, the correct option is C. '2 4 10'.
