Assertion: Boron is a good conductor of electricity.
Reason: Boron has a low ionization energy and a high electron affinity.
Both Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.
Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.
Assertion is true, but Reason is false.
Assertion is false, but Reason is true.
Boron is a poor conductor of electricity because it has no free electrons. The Reason, however, is true, as boron indeed has a low ionization energy and a high electron affinity.
