The correct answer is 96kmph.

Here's the step by step reasoning:

1. The design speed of a road is typically set higher than the speed of vehicles using it. This is to ensure safety and efficiency in traffic flow.

2. In this case, the speed of the overtaken vehicle is given as 80kmph.

3. Therefore, the design speed of the road must be higher than 80kmph.

4. Looking at the options, the only speeds higher than 80kmph are 96kmph, 100kmph, and 106kmph.

5. However, the design speed is usually not set too much higher than the speed of vehicles to avoid encouraging speeding.

6. Therefore, the most reasonable answer is the lowest speed that is still higher than 80kmph, which is 96kmph.
