Solution

The correct option is C Assertion is correct but Reason is incorrect
Chemical inertness= The noble gases were known as inert gases because of their perceived lack of participation in any chemical reactions, although some of them like $K r$ and $X e$ forms compounds.
Octet rule can't explain the shape and relative stability of the molecule,
So the correct option is [C].
