Answer 1

The correct answer is (d) Half-round country tiles

To explain: Half-round country tiles are laid in pairs of over-tiles and under-tiles. The under-tiles are laid with the concave surface upwards and the over-tiles are laid with the convex surface upwards. These tiles are similar to Spanish tiles.
