OG一题

Xiaotongdi

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 it was of earlier generations

我明白B为什么对，但是A为什么错？OG后面解释为没有主语和动词，需要咩？如果that改成the goal又对吗？
