Here is my reasoning of eliminated choices and doubts.
Experts please help.

A) Firstly heterotopias is not spaces . Moreover, "than" is used without any comparative form such as more/less - eliminated
B) Same reason as A. Also "as" is not making sense in the end - as immediately meet the eye - ELIMINATED
D) comma + that is incorrect . Also changes meaning with "relationship than other places" From original sentence, the comparasion is between layers . Also, which incorrectly modifies "places" instead of layers

Between C & E
Although E had multiple issues :-
Same modifier issue with hetertopias as in A B
E had incorrect idiom "more " and no than. Also use of , and Faucalt seemed not so correct.( is it correct?)
but the presence of "that" forced me to ignore the other two major issues with this option.
(Very very ridiculous reason , I know)

Also, I was doubtful that C is correctly applying ellipsis .
I dont get how ellipsis is correct in option C.

spaces that have more layers of meaning or relationships to other places than (layers of meaning or relationships to other places that) immediately meet the eye.
"that" is not present in sentence and I have read that ellipsis uses the part which is already been used in the sentence. So how is this correct ?
Please correct my understanding for such ellipsis usage.

Many thanks in advance!

These are all GMAT club test questions and all 700 level.
I seem to get almost all 700 level questions wrong. This is disheartening.

Can you please explain the correct ellipsis usage with correct version of this example.
