Answer:
As the device is intended to reduce the chance of collision between cars, the test used has to address this issue hence the answer is A. B tests the amount of damage which is not what the device is intended to do. C addresses the device functionality with respect to the speed of the car which is irrelevant as the device should reduce chance of collision irregardless of the car's speed. D would be useful to test the device although it will not be the most useful to test if the device works as intended, this would probably be used in a later stage of testing to determine the performance and consistency of the device, for example.

Hey!
Widespread exploration was made possible in the 1400s by the growth in wealth in Europe as well as new technological developments in ship building that made traveling far distances more attainable. The political regimes of Europe became more centralized at this time and were able to raise more funds to help support the acquisition of new trade routes and territories around the globe. New ships were built and developed at this time that also allowed for further international travel.
Hope this helps!
