Sentence Correction

Below is OG10 Q15. All the answer choices use being. But as discussed by many people, use of being is almost always wrong on GMAT. So just wanted to know under what conditions being as well as to be can be a correct choices.

In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings.
which may be violent without their being grounded in mental disease, from genuine manic-depressive
psychosis.

manic-depressive psychosis

Thanks

Any vîews...

I don't know why A is wrong. Can anyone please explain it?

Idiom
Distinguish between x and y
Distinguish X from Y

Eliminated - B, D, E

Now, we have only A and C

(A) mood swings, which may be violent without their being grounded in mental disease, from genuine
manic-depressive psychosis

(C) between mood swings, which may be violent without being grounded in mental disease, and genuine
manic-depressive psychosis

I believe "their" in A is unnecessary so eliminated

Ans C

You could have discussed this topic in the above thread instead of opening a new thread.


Anyways, to answer your question - you said- "use of being is almost always wrong on GMAT"

"almost always" doesn't mean Never

You can consider this example as a rare exception.

"to be" is also used as idiom in some cases :

ex : "believed to be"

you konw,there being```````/`````being+n./````being+adj./n.+being+done cannot be the right answer.
