所有格相关的代词指代_GWD3-Q4

In ancient Thailand, much of the local artisans’ creative energy was expended for the creation of Buddha images and when they constructed and decorated the temples that enshrined them.

1. much of the local artisans’ creative energy was expended for the creation of Buddha images and when they constructed and decorated  the temples that enshrined them
                   
2. much of the local artisans’ creative energy was expended on the creation of Buddha images and on construction and decoration of the temples in which they were enshrined
                   正确

我的问题: 如果代词指代句中的名词，而那个名词正好是所有格，是不是这种指代一定错，看到2个这样题目了

这个题目A选项，they想指代artisans

这题的主语是the local artisans' creative energy,所以B中they代指Buddha images
