Assertion : Tricyclopropyl methyl carbon...

Assertion : Tricyclopropyl methyl carbonium ion is more stable than tropylium ion.
Reason : Stability of tricycle propyl methyl carbocation is a result of conjugation between the bent orbitals of cyclopropyl ring and the vacant p-orbital of cationic carbon. ( `sigma` - resonance) : Both assertion and reason are correct, reason is the correct explanation of assertion, Both assertion and reason are correct and reason is not the correct explanation of assertion, Assertion is true reason is false, Assertion is false reason is true

A
