X, Y and Z are three alcohol isomers. X: $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}$ Y: $\text{CH}_3\text{CH}_2\text{CH(OH)CH}_2\text{CH}_3$ Z: $(\text{CH}_3)_2\text{C(OH)CH}_2\text{CH}_3$ Individual samples of each alcohol are heated with a mild oxidising agent and the observations are recorded. When dehydrated, one of these alcohols will form a pair of cis-trans isomers with molecular formula $\text{C}_5\text{H}_{10}$. Which row is correct?
