Hi Tushar,

In compound A there is no lone pair on N... so no resonance with the double bond.

In compound B two similar groups are present on N....they are CH3.....no stereoisomers.

In compound C as the N is having lone pair of electrons it will involve in conjugation with the double bond...making the molecule planar......no stereo isomers
