Paintings and sculptures on display in churches in the 15th century were_______.

A

collected from elsewhere.

B

made part of the buildings.

C

donated by people.

D

bought by churches.

　　---------------------------------

　　正确答案

本题考查推断。

由第四段开头提到的“they were not ‘collected’ either, but ‘site specific’, and were considered an integral part both of the fabric of the buildings”可知油画和雕塑并不是独立存在的，而是和建筑物联为一体、不可分割的，综上，B选项正确。

故正确答案为B项。
