Taste buds are onion-shaped structures with between 50 and 100 taste cells, each of them has
fingerlike projections poking through the opening located at the top of the taste bud called the taste
pore.           

(A) them has fingerlike projections poking through the opening located at the top of the taste bud
called the taste pore
(B) them that have fingerlike projections that poke through an opening located at the top of the taste
bud, which they call the taste pore
(C) which has fingerlike projections poking through the opening, called the taste pore, located at the
top of the taste bud
(D) which having fingerlike projections that poke through an opening, which is called the taste pore,
located at the top of the taste bud
(E) which have fingerlike projections that are poking through an opening located at the top of the
taste bud called the taste pore

答案为C选项，我的分析为：过去分词放在逗号有两种用法，第一是作为状语修饰前一句，逻辑主语为主句的主语，第二种用法是作为定语就近修饰逗号前的一个名词。这句each of which has fingerlike projections poking through the opening, called the taste pore, located at the
top of the taste bud中， called应该修饰opening, located at 应该修饰taste pore。
而PREP给出的分析为called和 located均修饰fingerlike projections，如果是并列修饰，中间应该有个逗号才对呀。。。已经凌乱了。求高人指明方向，小的感觉不尽！
