What will be the output of the following C code? int arr[] = {10, 20, 30, 40};…

The code initializes an integer array named arr with four elements: 10, 20, 30, and 40. The for loop iterates from i = 0 to i < 4, accessing each element sequentially using the index notation arr[i]. During the first iteration (i=0), it prints arr[0], which is 10. In the second iteration (i=1), it prints arr[1], which is 20, and so on until the fourth iteration (i=3), printing arr[3], which is 40. The printf statement outputs each number followed by a space, resulting in the sequence "10203040". Option A is incorrect because it lists the loop indices rather than array values. Option C is wrong as there are no syntax errors in this standard C code. Option D is incorrect because the code prints integer values, not variable names or string literals.
