(A) To determine the structure of $3,4-$dimethylpent$-1-$en$-3-$ol,we follow these steps:$1$. The parent chain is 'pent',which means it has $5$ carbon atoms.$2$. The suffix '$-1-$en' indicates a double bond at the $1^{st}$ position.$3$. The suffix '$-3-$ol' indicates a hydroxyl group $(-OH)$ at the $3^{rd}$ position.$4$. The prefix '$3,4-$dimethyl' indicates two methyl groups $(-CH_3)$ attached at the $3^{rd}$ and $4^{th}$ positions.$5$. Combining these,the structure is $CH_2=CH-C(OH)(CH_3)-CH(CH_3)-CH_3$.$6$. Looking at the options,the structure in image $814-a898$ correctly represents this molecule: a $5-$carbon chain with a double bond at $C1$,an $-OH$ group at $C3$,and methyl groups at $C3$ and $C4$.

The structure of $3,4-$dimethylpent$-1-$en$-3-$ol is:
