正确答案是B。后半句in which they were enshrined不懂。哪位高手帮忙解答下in在这里的作用是什么，which为什么指temples，为什么they能指代buddha images，这个句子到底是个什么句式。看不懂啊~~
这句话的意思是说：在古代泰国，当地大部分工匠的创作精力都花在了创作佛像、建造和装饰寺庙上，在那里佛像被供奉着。
in which they were enshrined，这句话的正常语序应该是：they(buddha images) were enshrined in (the temples). they指代buddha images, which 指代temples。in 之所以在这里是因为介词必须提前
