You are "so" lazy! --> "You are lazy" with more emphasis.

It's like the emphasizer "do": I do like you. --> "I like you" with more emphasis.

You are so lacking, and lacking so much...

The idiom you're thinking of is:

His knowledge springs not so much from experience as from schooling.

'such...as' is wrong.
'so ...as' is not wrong.

see a example from OG

Often major economic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in the financial markets.

Quickest approach:

The economy is ever more dependent, so the verb becomes in B and C should be becoming in order to reflect that the action is continuous. Eliminate B and C.

The following idioms are correct:

so X as to Y
so X that Y

In A, such a large degree as to make is not the correct idiom; the correct idiom would be so large a degree as to make. Eliminate A.

In D, lacking so much in math skills as to be difficult is not the correct idiom; the correct idiom would be so lacking in math skills as to be difficult. Eliminate D.

The correct answer is E, which uses the idiom so X that Y: so lacking in math skills that it will be difficult.

Hope this helps!
