In the reaction: $\text{Primary Amine} + CHCl_3 + KOH \rightarrow \text{Product}$,what is the product?

For the given compounds:
$I$: Pyridine
$II$: Pyrrole
$III$: $3$-Pyrroline
$IV$: Guanidine
The correct statement is:

The increasing order of reactivity of the following compounds towards reaction with alkyl halide is:

With respect to the following reaction,consider the given statements:
$C_6H_5NH_2 \xrightarrow{HNO_3, H_2SO_4, 288 \ K} \text{products}$
$(A)$ $o$-Nitroaniline and $p$-nitroaniline are the predominant products.
$(B)$ $p$-Nitroaniline and $m$-nitroaniline are the predominant products.
$(C)$ $HNO_3$ acts as an acid.
$(D)$ $H_2SO_4$ acts as an acid.

$CH_3NH_2 + CHCl_3 + KOH \rightarrow$ Nitrogen containing compound $+ KCl + H_2O$. The nitrogen-containing compound is:
