I got this question by my college director while I was bunking the class.

Query is from Instrumentation and Control in chapter Instrumentation and Control of Fermentation Technology

Correct answer is (a) Increases

For explanation I would say: The resistance of the material increases with an increase in temperature. This happens because the temperature is directly proportional to the change in temperature.
