JEE Main 2016 Chemistry question

Assertion: Among the carbon allotropes, diamond is an insulator, whereas graphite is a good conductor of electricity. Reason: Hybridization of carbon in diamond and graphite are and respectively.

(1)Both assertion and reason are correct, but the reason is not the correct explanation for the assertion.Correct
(2)Both assertion and reason are correct, and the reason is the correct explanation for the assertion.
(3)Both assertion and reason are incorrect.
