Assertion: The resistivity of a semiconductor increases with temperatu

1.	Assertion: The resistivity of a semiconductor increases with temperature. Reason: The atoms of a semiconductor vibrate with larger amplitude at higher temperature therby increasing it resistivity.A. If both the assertion and reason are true and reason is a true explanation of the assertion.B. If both the assertion and reason are true but the reason is not the correct explanation of assertion.C. If the assertion and reason are falseD. If both the assertion and reason are false.
Answer» Correct Answer - D (d) Resistivity of a semiconductor decreases with the temperature. The atoms of a semiconductor vibrate with larger ampliutes at higher temperatures thereby increasing its conductivity not resistivity.
