D Correct answer
Explanation

Fiber optic transmission offers all three advantages: it is resistant to data theft (tapping fiber requires physical intrusion that breaks transmission), provides very high data rates (gigabits per second), and has low noise (immune to electromagnetic interference). Therefore 'All of the above' is the correct choice.
