Which of the listed conditions describes the effect on intrinsic semiconductor operation as a result of a temperature increase?

Correct Answer: Option D — Conductivity will increase

In intrinsic semiconductors, increasing temperature provides thermal energy that promotes electrons from the valence band to the conduction band. This increase in free charge carriers significantly reduces the material's resistance, thereby increasing its electrical conductivity, a phenomenon that must be considered when designing electronics for high-temperature engine room environments.
