(A) The orbital interaction involving the delocalization of electrons from a $\sigma$ bond (usually $C-H$ or $C-C$) into an adjacent empty or partially filled $\pi$ orbital or $p$-orbital is defined as hyperconjugation.This effect is also known as the $\sigma-\pi$ conjugation or the $Baker-Nathan$ effect.Therefore,the correct option is $A$.
