The growth of the railroads led to the abolition of local times, which was determined by when the sun reached the observer's meridian and differing from city to city, and to the establishment of regional times.
A. which was determined by when the sun reached the observer's meridian and differing
B. Which was determined by when the sun reached the observer's meridian and which differed
C. which were determined by when the sun reached the observer's meridian and differing
D. determined by when the sun reached the observer's meridian and differed
E. determined by when the sun reached the observer's meridian and differing

答案是E， 我选了D， 为什么后面要用differing不可以用differed啊，这样不是不平行了么？
请指教！！

differed 的话后面半句从句就是 which was differed from city to city。不通了。平行不是这么绝对的。

times differ from... 主动关系 用现在分词
