Solution

The correct option is A Both Assertion and Reason are correct and Reason is NOT the correct explanation of Assertion
Assertion: Hydrogen has a lower ionization energy than does helium. Because noble gas helium with most stable electronic configuration resists the ionization.
Reason: Polar covalent bonds are formed by the hydrogen with halogens.
Two atoms with different electronegativities form polar covalent bonds.
Hence, both assertion and reason are correct but reason is not correct explanation of assertion.
