OG82 句子结构问题

茉莉蔷薇

82. Accordingtoarecentpoll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.
A.    like that of earlier generations
B.    as that for earlier generations
C.    just as earlier generations did
D.    as have earlier generations
E.    as it was of earlier generations

大家关于A的讨论很热烈啊，但是就OG的解释，我有个问题向大家请教
OG说 the second part of the sentence must have the same structure as the first part. 是说在这句话中，比较的时候前后的句子要有相同的句子结构，还是说在所有的这种前后表示对比的句子中结构都必须对应啊？

比较中的句子结构/逻辑必须对等
其他的 比如用 ,but  ,and 等连接时也要求对等
manhattan上有讲
