OG85 LIKE&AS

猫小雯雯

OG85. According to a recent poll, 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 generation              （E）

不知道A错在哪里呢？这里that为什么不能指代a goal呢？句意就是：像上一代的人的目标一样，年轻人的目标是拥有和居住着一个房子。
为什么要用as的句子结构呢？谢谢解答
