Can anybody please tell me the difference between the two figure of the NMOS transistor and what does body of each transistor determines about each transostor output....

Thanks in advance
 

Can you make out a bigger and clearer picture?
It is difficult to see what is what.
 

the top transistor in fig. 1 requires a triple well process to isolate its body from the underlying p-type substrate (body of bottom transistor).

fig.2 can use a simpler process but suffers from body effect.
 

For the first figure: the body effect is eliminated by a triple well process whereas in the second figure body effect is present

Body effect affects the threshold voltage of the transistor; in this case the NMOS. In simpler words a larger gate source voltage is required to turn ON the transistor
