我选E.

例如：

Retinal pigment epithelium cells in cultured specimens showed no RPE65 immunolabeling, but expressed immunolabeling for ED-1 indicating phagocytic activity of these cells in vitro. 用google找得。

感觉and 和but 做连接词用法应当一样，如果前面有逗号，最好用完正句。

特殊情况是：V1,V2,and V3

否则，一般是s+v1, and S+v2

大家探讨。。。

"Rossicci said he closed his downtown restaurants after falling months behind
            in rent to his landlord, Empire Properties."

"It was falling months behind in filing, and physicians were dissatisfied because charts were not always readily accessible."

1.But 之后，确实是“最好”用完整句

2.根据以上两句以上Google结果，E优选过C项

Plus, google搜索结果"falling months behind in its" ，没有结果
