Answer

Brief Explanations:

The line "We have to use a spell to make them balance: 'Stay where you are until our backs are turned!'" uses the playful idea of a "spell" and the humorous command to the stones, which shows amusement. The other options either focus on the physical labor ("We wear our fingers rough..."), the mystery of the gaps ("No one has seen them made..."), or the neighbor's repetitive saying ("Good fences make good neighbours") without the same tone of amusement.

Answer:

We have to use a spell to make them balance: "Stay where you are until our backs are turned!"
