问一道【比较/代词】题，谢谢！

Like the one reputed to live in Loch Ness, also an inland lake connected to the ocean by a river, inhabitants of the area around Lake Champlain claim sightings of a long and narrow “sea monster.”

(A) Like the one reputed to live in Loch Ness, also an inland lake connected to the ocean by a river, inhabitants of the area around Lake Champlain claim sightings of a long and narrow “sea monster.

(B) Inhabitants of the area around Lake Champlain claim sightings of a long and narrow “sea monster” similar to the one reputed to live in Loch Ness, which, like Lake Champlain, is an inland lake connected to the ocean by a river.（正确）

(C) Inhabitants of the area around Lake Champlain claim sightings of a long and narrow “sea monster” similar to Loch Ness’s, which, like Lake Champlain, is an inland lake connected to the ocean by a river.

(D) Like Loch Ness’ reputed monster, inhabitants of the area around Lake Champlain, also an inland lake connected to the ocean by a river, claim sightings of a long and narrow “sea monster.”

(E) Similar to that reputed to live in Loch Ness, inhabitants of the area around Lake Champlain, also an inland lake connected to the ocean by a river, claim sightings of a long and narrow “sea monster.”

我的疑问：这个题考的是比较，但我的问题在于E选项。OG排除E的解释是（1）比较的对象错误了（这个我可以理解）；（2）Similar to that reputed to live in Loch Ness is needlessly wordy and indirect。这句话什么意思呢？正确选项B中用的是one而非that，是因为代词的原因吗？我觉得不太可能是这个短语的结构，因为B中也有这个结构（红色字），E只是把这个结构提前了。万分感谢！！
