As we have learnt,

Secondary amines can be prepared by reduction of isocyanide 

Isocyanide group is reduced to NHCH3  \mathrm{(2\degree\:Amine)}  group by \mathrm{LiAlH_4} or by catalytic hydrogenation. 

\mathrm{R-N^\oplus\equiv C^\ominus\xrightarrow[Ether]{LiAIH_{4}}R-NH-CH_{3}}

Oximes, amides and nitriles form primary amines as given below

Hence, the correct answer is Option (4)
