cell constant is maximum in case of

1)wire of length 100m and cross sectional area 100m^2
2)wire of length 10m and cross sectional area 10m^2
3)one meter cube of a material 
4)equal in all cases 

Dear Student,
Cell constant K=lA 
the units are m-1 , cm-1 
putting the value of each case given above we find that the cell constant comes to be 1 equal in all cases hence option (4) is correct.
