(C) The reaction between melamine ($2,4,6-$triamino$-1,3,5-$triazine) and formaldehyde proceeds via a nucleophilic addition reaction to form a methylol derivative. Specifically,the reaction of one molecule of melamine with one molecule of formaldehyde yields monomethylol melamine,which acts as an intermediate in the synthesis of melamine-formaldehyde resin. The structure shown in option $C$ represents this monomethylol melamine intermediate,where one of the $-NH_2$ groups has reacted with formaldehyde to form $-NHCH_2OH$.
