Consider the Hofmann ammonolysis reaction :
`R-X +ddotNH_(3)rarr underset(1^(@) amine)(HX + RNH_(2)) overset(R-X)underset(373K)rarr`
If `R = Me_3 C - (t-butyl)`, the correct order of basic character of the above amines in aqueous medium is :
A. `NH_3 gt 1^@ gt 2^@ gt 3^@`
B. `3^@ gt 2^@ gt 1^@ gt NH_3`
C. `1^@ gt 2^@ gt NH_3 gt 3^@`
D. `1^@ gt NH_3 gt 2^@ gt 3^@`
