Dear studentforce equation at 2m2mg-T=2ma1force equation at mmg-kx=ma2(T is tension and a1 and a2 are corresponding accelarations)equations have been writen considering a1 and a2 downwards
just when the blocks are released, x=0, kx=0so, a2=gand, T=kx=0so, 2mg-T=2ma1a1=gso, option a is correctRegards
