(D) The reaction involves the acid-catalyzed cyclization of $2,7-	ext{dimethyl}-2,6-	ext{octadiene}$.First,the protonation of one of the double bonds forms a tertiary carbocation.Then,an internal nucleophilic attack by the other double bond occurs,leading to the formation of a five-membered ring with a tertiary carbocation.Finally,the loss of a proton $(-H^{+})$ from the carbocation results in the formation of the major product,which is $1,1,2-	ext{trimethyl}-2-	ext{isopropylidenecyclopentane}$ (or a similar isomer depending on the specific mechanism path).Looking at the final structure shown in the mechanism: the product is $1,1-	ext{dimethyl}-2-	ext{isopropylidenecyclopentane}$.In this structure,the double bond is between the ring carbon and the isopropylidene carbon.This double bond involves $2$ carbon atoms,both of which are $sp^2$ hybridized.Therefore,the major product has $2$ $sp^2$ hybridized carbon atoms.
