Explanation:

To solve this, we analyze each option:

• Option a: The arches here are typical of Gothic architecture (pointed arches), but the question likely focuses on unique decorative elements.
• Option b: The "triangles" on middle columns are small and not the main decorative focus.
• Option c: The sculptures (row of figures) and the rose stained - glass window (the circular, detailed window) are key decorative and artistic details of Gothic cathedrals (like Notre - Dame - style architecture), which are prominent features.
• Option d: Since option c is valid, d is incorrect.

Answer:

c. the details of the sculptures and the rose stained glass window
