Answer
Exam answer
(d) 100.
Explanation
Multiply rows x columns x size of one element. The array is 5 x 5 = 25 elements, and each int occupies 4 bytes, so 25 x 4 = 100 bytes. Option (a) is the count of elements rather than bytes — a common slip. The same method works for any type: change only the 4 (double would give 25 x 8 = 200 bytes, which is why option (b) is offered).
In words
100.
