【求教】prep12#105-V+ing的时态问题

第一次发帖，向大神们求教。
prep12里面第105题
Beatrix Potter, in her book illustrations, carefully coordinating them with her narratives, capitalized on her keen observation and love of the natural world.(A) Beatrix Potter, in her book illustrations, carefully coordinating them with her narratives,
(B) In her book illustrations, carefully coordinating them with her narratives, Beatrix Potter

(D) Carefully coordinated with her narratives, Beatrix Potter, in her book illustrations
(E) Beatrix Potter, in her book illustrations, carefully coordinated them with her narratives and

其中的A选项，解释里面说use of the present progressive form of the verb confuses the sequence of time with respect to the past tense of the main verb capitalized.
