Answer:

D. They represented the power of the Church.

Brief Explanations:

In medieval society, the Church held great influence. Cathedrals, as large and prominent religious buildings, were symbols of the Church's authority and power. While options A (long construction time), B (paid by ordinary people), and C (new architectural styles) may be facts about cathedrals, they do not directly address their significance in terms of the role and power of the Church in medieval society. The Church was a central institution, and cathedrals were physical manifestations of its power, making option D the most relevant answer.
