Ciel少爷考GMAT

A study on couples' retirement transitions found that women who took new jobs after retiring from their primary careers reported high marital satisfaction, more than when retiring completely.
　　(A) more than when retiring
　　(B) more than if they were to retire
　　(C) more so than those who retired
　　(D) which was more so than those retiring
　　(E) which was more than if they had retired


这道题选C。
其它选项我都能理解，就是C里的“more so than" 这个表达感觉怪怪的。more than 之间为什么要夹 so呢？之前也没看到过这种表达方式。
求教知道的大神！谢谢了！

"It is an idiom. It is used in making a "more than" type of comparison where you also want to refer to a previously stated verb / action (that's where the "so" comes in). In this case, the "so" refers to "reported high marital satisfaction.""
