                        \[{{N}_{2}}\]gas will not be evolved upon reaction of\[HN{{O}_{2}}\]with which of the following amines

A) \[{{1}^{o}}\]                       

B)      \[{{3}^{o}}\]                       

C) \[{{2}^{o}}\]                       

D)       Bothe (b) and (c)

Correct Answer: D
