Dear piyush

rn

Electric field lines flow from low to high potential.

rn

so work will have to be done in the direction of electric field for moving a negative charge.

rn

so only A,B,and C paths are possible.

rn

also W=qVb-Va

rn

and the difference of potential is max in case of path B.

rn

SO max. work will be done in path B.
