Usage of "the same as in" and "the same as of"

Question

The following sentence is on an article of Khan Academy:

"Which properties of circle B are the same as in circle A?"

I thought the following sentences may have the same meaning as above:

Which properties of circle B are the same as of circle A?
Which properties in circle B are the same as in circle A?
Which properties in circle B are the same as of circle A?

My question is:

Do you think each sentence is correct and natural?

It should really be "of" not "in" for both, as long as it does not actuallly mean "in".

"A property of x" denotes that "x has the property", "the property belongs to x" which is the case when you are discussing mathematical objects.

Thank you for answering. Do you think the sentence 2 are correct and natural? @David Siegel seems to find "the same as of" in the sentence incorrect.(https://ell.stackexchange.com/a/270455/127344) – catwith Dec 31 '20 at 02:08
@user13651701 "the same as those of" is probably better. – Prime Mover Dec 31 '20 at 07:11

Sentence 2 strikes me as awkward at best. "...the same as of circle A" just feels incorrect at the second "of"."same as of" just does not work, in my view.

Sentence 3 seems correct, but different in meaning. "Properties in circle A" would seem to be properties included in A, not aspects of A.

Sentence 4 has the same problem as 2, plus the same issue with "properties in" as 3.

I would recast 1 as:

"Which properties of circle B are also properties of circle A? .
