For your personal safety, what should you do before you get into your car?
a. check the air in your tires.
b. check under the car and in the back seat.
c. get in your car quickly and lock the doors.
d. look under the hood.

This really depends on context XD 
ALWAYS check your backseat, especially if it is night and/or you are in a shady part of town. Under your carprobably not the best idea, you could be vulnerable while bending down, and someone under your car is more likely to get run over by you than try anything...lol
But in general car safety they always tell you to check your tires, because a flat can make you spin or flip depending on your speed
I'd just go with the context of the lesson/test on this one, between those two answers :)
