The total number of amines among the following which can be synthesized by Gabriel synthesis is ________.

Gabriel phthalimide synthesis is used to prepare $1°$ aliphatic/alicyclic amine in common.

Hence, amine which can synthesised by Gabriel phthalimide synthesis method is:

(A) ${\mathrm{Me}}_2\mathrm{CH}-{\mathrm{CH}}_2-{\mathrm{NH}}_2$

(B) ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{NH}}_2$

(C) $\mathrm{Ph}-{\mathrm{CH}}_2-{\mathrm{NH}}_2$
