If the net force on a body is zero and if it is moving, it will stop , is it true or false? plzzz help

Theoretically not. It will continue to move. As Issac Newton once supposedly said: "Hmmm... if body in motion it stays in motion...". He never considered that the space it's moving through could become curved and this is where Albert Einstein comes in and I must go.

false..it wont stop because there is no net force acting upon it which can change its state of motion...no net force acting on a body means that there is no change of state in motion...since the body is moving, it will stay in that state of motion

No it will not stop.
Start with Newton's famous "F = ma", i.e. force equals mass, times acceleration.
If "F" is zero, then "ma" has got to be zero. Given that "m" is not zero (nothing is massless), then "a" has got to be zero. If the acceleration, "a", is zero, then the speed cannot change. If the speed cannot change, then the object cannot stop.

Newtons First Law:
"A body in uniform (unchanging) linear motion will continue in that motion UNTIL acted on by an outside force."
A moving body, with NO forces acting on it will continue to move until an outside force stops it.

Assuming there is no friction (which would be a force) in your world it will never stop.
conservation of energy
conservation of momentum

it will stay in motion.. only external force can change the conditon of objects

It alway keeps it's state
mean that the question is false
