In the given reaction,$A$ is:
$A$ $\xrightarrow{\text{Reduction}} B$ $\xrightarrow{HNO_2} C_2H_5OH$

Identify $C$ in the following reaction sequence:
$Cyclohexanone$ $\xrightarrow[\text{Alkaline medium}]{HCN} A$ $\xrightarrow{LiAlH_4} B$ $\xrightarrow{NaNO_2/HCl} C$

The number of primary,secondary,and tertiary amines possible with the molecular formula $C_3H_9N$ is:

Match the compounds given in List-$I$ with their characteristic reactions given in List-$II$. Select the correct option.

List-$I$ (Compounds)	List-$II$ (Reactions)
$A. \ CH_3(CH_2)_3NH_2$	$(i)$ Alkaline hydrolysis
$B. \ CH_3C\equiv CH$	$(ii)$ With $KOH$ (alc.) and $CHCl_3$ produces bad smell
$C. \ CH_3CH_2COOCH_3$	$(iii)$ Gives white ppt. with ammoniacal $AgNO_3$
$D. \ CH_3CH(OH)CH_3$	$(iv)$ With Lucas reagent cloudiness appears after $5 \ minutes$

Given below are two statements:
Statement-$I$ : Oxidation of $p$-nitrotoluene with acidic $KMnO_4$ gives an acid that is stronger than benzoic acid.
Statement-$II$ : Reduction of $p$-nitrotoluene with $Sn/HCl$ followed by neutralization gives an amine that is more basic than aniline.
In light of the above statements, choose the most appropriate answer from the options given below.
