The whole point of analogies like this is to choose pairs where the first and the second word have the same relationship in both pairs. So the relationship between A and B have to be the same as the relationship between C and D, right? So look at this example.
What is the relationship between a gardener and a hoe? Well, the gardener uses the hoe as a tool in the course of doing his or her job.
So now you need another example where the first word uses the second word as a tool in the course of doing its job. Among the choices you've given, D is the best answer -- a seamstress uses a scissors as a tool in the process of doing her job.
Painters don't usually actually use plaster to make their paintings. A judge's ruling is pretty much what they are trying to make, now what they use to make it.
