Expert Answer:

Resonance effect stabilize carbocation as the conjugation with a multiple bond or lone pairs of electrons increase the stability of a carbocation. Hence,  allylic and benzylic systems are more stable than their saturated counterparts.

The heteroatoms such as N, O are electron rich with lone pair of electrons which results into resonance effect. This resonance stabilize carbocation. Therefore, carbocation invoving in heteroatom resonance is more stable than the saturated tertiary carbocation.
