怎么理解og12－39的解释

chamcham

In 1527 King Henry VIII sought to have his marriage to
Queen Catherine annulled so as to marry Anne Boleyn.
(A) so as to marry
(B) and so could be married to
(C) to be married to
(D) so that he could marry
(E) in order that he would marry
答案是D
关于这个题，前人对A和D做了很多分析，我看了很有收获。但是，对于og的一条解释，我不能理解，og说c选项，应该加in order变成in order to，为什么呢？以下是og的解释：

C The infinitive here should be preceded by a
conjunction (in order); to marry is preferable
to the wordier to be married to.

我的理解是C的问题不在于to还是in order to，问题的关键是be married to不对，marry不用被动
