All others have idiom issue

A...
B. even so much as
C. so much as even
D. even as much that
E. even so much for

How does the repertoire of 10,000 songs compare to how much the musician can remember?
Someone explain please...

OA will follow.

I went with C; what's wrong with that choice?

Right idiom is
So X as to Y OR
So X as to be Y

C misses this. Hope this helps!!

'so much as' is idiomatic but should not be used to quantify nouns
'so much as' usages
https://idioms.thefreedictionary.com/so+much+as
1. but rather - I'm not looking at her so much as I am studying her hat.
2. even - From outside, no one could see so much as a light on in the house.

'as much as' is correctly used here to quantify the noun

Interestingly in GMAT 'so much as' is almost always incorrect.

Likely correct '..so..' combinations:
'...so...that...'
'...so much as to be...'
'just as... ,so...'
'not so much... as...'
'so ...as to be...'
'so ...as not to be...'
