I think the key is, it's easy to get "self-driving" where the car will hand off to the driver working on highways. "Follow the lines, go forward, don't get hit". But having it DRIVERLESS is a different beast, and the failure states are very different than those in surface street driving.
Ignoring that, NONE of those answers are correct. It wants "C) Psychology focuses on genetic makeup, while sociology focuses on social interactions.", but that's not a true statement. Psychology is absolutely not focused on genetic makeup.
