Which of the following cannot be obtained by the reduction of an aldehyde or a ketone using $NaBH_4$ or $LiAlH_4$?

Give the conversion of the following:
$(i)$ $but-2-enal$ from $ethanal$
$(ii)$ $Methyl$ $benzoate$ from $benzaldehyde$

An organic compound $X$ is oxidised by using acidified $K_2Cr_2O_7$ solution. The product obtained reacts with phenyl hydrazine but does not give the silver mirror test. The compound $X$ is,

The end product in the following sequence of reaction is
$HC \equiv CH$ $\xrightarrow{1\% \, HgSO_4, 20\% \, H_2SO_4} A$ $\xrightarrow{CH_3MgX} B$ $\xrightarrow{[O]}$

Given below are two statements:
Statement $I:$ The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions.
Statement $II:$ The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of $H$-bonding.
In the light of the above statements,choose the most appropriate answer from the options given below:

Which of the following is the Wolff-Kishner reduction?
