请问，动名词短语是就近修饰还是修饰主语？还是从句的主语？

例如，Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.
A.        which would rob the oysters there of their flavor, and to make them decrease in size
B.        and it would rob the oysters there of their flavor, make them smaller
C.        and rob the oysters there of their flavor, making them decrease in size
D.        robbing the oysters there of their flavor and making them smaller
E.        robbing the oysters there of their flavor, and making them decrease in size

答案是D，可是我选的A。。
我发现好多考察逻辑意思的改错都涉及动名词短语的修饰，可是有点搞不清楚。。跪求大神帮助

首先A中which refer to ABay造成后面的意思肯定是错的。 and前后不构成平行错误
其次robbing and making平行，同时修饰了前面一句话

所以这里动名词短语修饰的前面一句话？那如果    主句，which、、、，Ving。。。这种结构里面，动名词短语修饰的是which引导的从句，还是主句呢？
