However, apparently this is wrong. The correct answer is A - Restrict the available drive allocation on personal computers.
Not quite sure I get this. Of course you can disable all USB ports from data sticks - my organisation does it and we can still use USB keyboard and mice. This is wrong in my view. The best way to prevent use of USB drives to copy files is to disable USB ports across the entire business.
