Temperature is actually a measure of the kinetic energy (motion energy) of particles. As temperature increases, kinetic energy increases proportionally (because they really are one in the same). An increase in kinetic energy corresponds to higher-energy movement, or faster particles. 

The answer is D.

When the temperature increases,
D) the object's particles move faster.

They also move farther apart. When objects heat up, the particles spread out and take up more room. When objects are heating up, they expand. When they cool down, they contract.

Hope this helps! :)
