C.pump blood more efficiently
Hello!
We can cancel out C because most people don't crash during the day. That leaves us with 2 reasonable answer choices. We can cancel out A because yes, it is a long trip, however, when you are closer to home you think you are safe and start falling asleep or even driving more recklessly. So that leaves you with your best answer choice.
I am, yours most sincerely,
