Before the string is cut the force applied by the spring is 3mg and tension in string is mg
Once the spring is cut, the tension comes to zero suddenly,
Thus acceleration of block b gets g downwards,
Whereas acceleration of a becomes g/2 upwards because the force from the spring is still the same at the moment the string is cut.
Once the spring is cut, the tension comes to zero suddenly,
Thus acceleration of block b gets g downwards,
Whereas acceleration of a becomes g/2 upwards because the force from the spring is still the same at the moment the string is cut.

I think it should be (c) B must fall with the acceleration g( it's under free fall) and for A,,F=kx =>2Ma=kx(if we assume that initially the system is in equilibrium)((Mg=kx=>x=Mg/k)) =>2Ma=kMg/k =>a=g/2
