求版主解答一个OG17的语法问题

小灰灰养大鸟

According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is good for cardiac health.

(A) wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is
(B) wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be
(C) wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be
(D) total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be
(E) total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is


B选项的more of a kind of fat 中的of为啥会存在啊
have less total fat ... and more a kind of fat 不就已经平行了吗？
这个of是什么意思啊？


十分感谢~!

谢谢！！所以more of 后面也就没有than了，因为这里不是比较级，只是一个have sth（more of）的结构。
十分感谢！
