Which of the following amines form $\mathrm{N}$-nitroso derivative when treated with ${\mathrm{NaNO}}_2$and $\mathrm{HCl}$

2° Amine produces N-nitroso derivative. When secondary amines are combined with NaNO2 and$\mathrm{HCl},$ they produce an N-nitroso derivative.
A secondary amine is represented by Option C.
As a result, it produces an N-nitroso derivative when exposed to ${\mathrm{NaNO}}_2$ and
