Difficulty using dnd-kit

[SyneosLee]

I am trying to create a fairly simple exercise using dnd kit, but am having some real issues trying to work out how to achieve it, and to navigate around the docs. I have to produce a quiz question similar to what is attached. There are 4 draggables and 4 doppables. Any droppable can receive any draggable. Once in place, the user would need the ability to drag an item out of a droppable to reset it.

Does anybody have any ideas? There seems to be a lot of list sorting examples but not many drag and drops.

Please, if any

one can help I would be very grateful!!
