Identify the set in which $X$ and $Y$ are correctly matched for the reaction of benzaldehyde with a reagent $X$ to form product $Y$.

In the above chemical reaction sequence,"$A$" and "$B$" respectively are:

Which of the following compounds will give a positive iodoform test?

Which of the following gives a positive iodoform test? The reaction is shown below:
$2,3,5-\text{trimethylhepta-2,4-diene} \xrightarrow[(2) H_2O/Zn]{(1) O_3} X (C_3H_6O) + Y (C_3H_4O_2) + Z (C_2H_4O)$

Statement $I$: Aldehyde on reaction with $HCN$ gives Cyanohydrin.
Statement $II$: Cyanohydrin is a compound which consists of hydroxy and cyano groups on the same carbon.
