If a D.C. shunt motor is working at full load and if shunt field circuit suddenly opens?

This will make armature to take heavy current, possibly burning it
This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses
Nothing will happen to motor
Motor will come to stop
