The odd one out is D. Pen : Pencil.
In all the other options, the first item is a tool that is used to work on the second item. For example, a shovel is used to work on mud, a screwdriver is used to work on screws, and a hammer is used to work on nails. However, a pen and a pencil are both writing instruments. They can be used to write on paper, but they are not used to work on each other.
