As we have learned

Hyperconjugation or σ-π resonance or Baker and Nathan effect -

The conjugation between \alpha C-H sigma bond and adjacent  multiple bond or carbocation is called Hyperconjugation.

- wherein

It is permanent effect.

 Definition of hyperconjugation 

Hyperconjugation-The delocalization of sigma electrons(usually C-H & C-C)into the adjacent pi orbital or empty or partially filled p orbital.Example hyperconjugation in propene.
Since there is no definite bond between carbon atom & one of the hydrogen atoms in the hyperconjugation forms,hyperconjugation is also called no-bond resonance.

Therefore, option (4) is correct.
