When car tires are on hot pavement for too long, the pressure inside will and the volume within the tire will a) increase; decrease due to deflation b) decrease; remain unchanged c) increase; increase and possibly result in a blowout d) increase; remain unchanged as long as the temperature is constantly rising

When the car is driven at high speed for a long time on rough pavement,
the tires and the air inside them heat up. 

That causes the air pressure inside the tires to increase, and the increased
pressure tries to make the tires bigger (they ARE made of rubber, after all).

Normally, the tires do expand a little.  But if this goes on for too long, or
if there's a weak spot on the tire, a blowout is possible.
