1. "possibly" has a different meaning from "can"
2. it is "the number of chirps xxx" that "serve" xxx, not the action of "rises and falls"

我觉得用现在分词，意思上也是可以的，但是现在分词是句子的简化形式，他在某些简单情况下可用，并不是所有的句子都适合简化为现在分词形式，像本例，还要表达can，或者possible的情态动词，就不适合简化为分词结构了

I would take E) it were written as "possibly serving".
In addition, "in fact possibly serving" is awkward and change the original meaning.
