1) This is a Carbalamine reaction  and A will be CH3CN which when reacts to a metal will give CH3CH2NH2. You can read more about it here http://en.wikipedia.org/wiki/Carbylamine_reaction

 

2) CH3CH2CN + Na + CH3CH2OH ---> CH3CH2NH2  (A)

so, now

CH3CH3NH2 + NaNO2 + HCl ----> CH3CH2N2+}Cl- (B)

HI Upasana,
 
I am sorry but the queries seem wrongly formulated...
 
For 1) CH3NH2 is a carbylamine reaction giving an isocyanide CH3NC, which on reduction with Na/EtOH would give CH3NHCH3 (dimethylamine). I am not sure if the question is if CH3NC gets reduced or its an independent question.
 
For 2) CH3CH2CN on reduction would give propyalmine (CH3CH2CH2NH2) and which with NaNO2/HCl give CH3CH2CH2OH (n-propanol). HOwever, here too I am unsure if the 2nd part of question is a follow-up on the 1st  part
 
CH3CH3CN cannot give A (CH3NC) by reduction...!!
