Observe the following set of reactions. What are $X, Y$ and $Z$ respectively?

Clemmensen's reduction will convert cyclohexanone into

The molecular formula of compound $A$ is $C_2Cl_3OH$. It reduces Fehling's solution and on oxidation gives a monocarboxylic acid $B$. Compound $A$ is obtained by the reaction of chlorine with ethyl alcohol. What is $A$?

The major product $Y$ in the following reaction is:

Given below are two statements: Consider the following reaction: $R_2C=O + H_2O \rightleftharpoons R_2C(OH)_2$.
Statement $I$: In the case of formaldehyde $(HCHO)$,$K_{eq}$ is about $2280$,due to small substituents,hydration is faster.
Statement $II$: In the case of trichloroacetaldehyde $(CCl_3CHO)$,$K_{eq}$ is about $2000$ due to the $-I$ effect of $-Cl$ atoms.
In the light of the above statements,choose the correct answer from the options given below:

In the given reaction,what is $y$?
$CH_3CH_2COCH_2COOH$ $\xrightarrow{\Delta} x$ $\xrightarrow[(ii) H_2O]{(i) LiAlH_4} y$
