C.

BDE are out due to unidiomatic.

between A and C:
A is wordy because of with clause and 'their'.

I don't regard distinguish between .. and.. and distinguish ... from... as a test point of GMAT. their differences are debatable and too subtle.

Since there is only 2 psychological notions here (mood swings & psychosis) we use the idiom distinguishes from....

distinguish x from y

therefore, only AD are out. Why are B and E wrong?

Can any expert explain the difference between

Distinguish X from Y and
Distinguish between X and Y

Furthermore, if we remove unnecessary-"their" from option (A). will the option be correct?

Hi,
Distinguish X from Y and Is used for 2 pretty similar items
Distinguish between X and Y Is used for 2 very different items

As it was said before the difference between <Distinguish X from Y> and <Distinguish between X and Y> is too subtle.

B, D, E are out because they use neither <Distinguish X from Y> idiom nor <Distinguish between X and Y>.
A - <their> is bad -> out.

Leaves us with C.

If we remove <their> from A, seems to me, it will be correct option.
But if I am not mistaken, <Distinguish between X and Y> has a small priority over <Distinguish X from Y>.
So we will have to choose option C once again.
Correct me, please, if I am wrong.
