Is it d or a
trip planning reduce

driving distance
the chance of collision
insurance costs
rest area stops

Hm. Trip planning could help reduce rest area stops because you already know what you need or have what you need. But, I believe driving time would always be the same unless you take backroads or quicker routes. I would say it is D, but I am not 100% sure. I hope this helps! :)
