here option b is correct as chlorine is weak ligand and the electron in 3d subshell will not pair up so no. of unpaired electron will be 2 so by applying formula of mag moment we get 2.82 as the general confg of Ni is 4s2.(3d8)and here it is in +2 state so its confg. will be 3d8 now in 3d subshell as mentioned above the unpaired electron will be 2.
