Which of the following reactions is an example of Clemmensen reduction?

Identify the compounds $A$ and $B$ involved in the formation of given aldol

The products $C$ and $D$ are

$$ \text { Toluene } \xrightarrow[\text { (ii) } \mathrm{H}_3 \mathrm{O}^{+}]{\text {(i) } \mathrm{CrO}_2 \mathrm{Cl}_2 / \mathrm{CS}_2} X \xrightarrow{\text { Conc. } \mathrm{NaOH}} Y+Z $$

The correct statements about $Y$ and $Z$ are

A. $Y$ is a secondary alcohol.

B. $Y$ is the reduction product of $X$.

C. $Z$ on heating with sodalime gives benzene.

D. $Y$ does not give $\mathrm{H}_2$ gas with Na metal.
