Answer / j.karthik

Ground:
It doesnot give a zero reference point of the voltage
It doesnot maintain a voltage stability of the system
If any fault happens in the system means then the fault
current will passes to the ground terminal.

Neutral:
It gives a return path of current.
It maintains the voltage stability of the system.
It gives a zero reference point of the voltage.

NOTE:
In Practically the Neutral wire is connected to Earth
in the nearest substation.....
