But-1-ene and but-2-ene are treated separately with cold, dilute acidified manganate(VII) ions. Four students, W, X, Y and Z, make statements about these alkenes and the diols formed from them. W One diol contains two primary alcohol groups. $$\(X\)$$ One diol contains a primary and a secondary alcohol group. Y One diol contains two secondary alcohol groups. Z Both alkenes exhibit cis-trans isomerism. Which two students are correct?
A.
\(W\) and \(Y\)
B.
W and Z
C.
\(X\) and \(Y\)
D.
\(X\) and \(Z\)
