The correct answer is: D. None of these.
Form T/D 912 is a temporary driving permit issued to drivers who have been convicted of a driving offense and have had their license suspended. The permit allows the driver to drive for a limited period of time, but there are restrictions on the speed they can drive. The speed limit for drivers with a Form T/D 912 is the same as the speed limit for all other drivers.
Option A is incorrect because the speed limit for drivers with a Form T/D 912 is not 15 kph.
Option B is incorrect because the speed limit for drivers with a Form T/D 912 is not 20 kph.
Option C is incorrect because the speed limit for drivers with a Form T/D 912 is not 25 kph.
