The correct answer is:

When a modest amount of energy is applied to semiconductors, electrons quickly travel to the conduction band and are then free to move across the crystal's lattice.

If thermal energy is provided, the conduction of electrons will increase. Hence, as the temperature is increased, the resistivity of the semiconductor is decreased according to the following diagram:
