More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

(A) More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

(B) With 20 percent of the world's fresh water, that is more than all the North American Great Lakes combined, Siberia's Lake Baikal has more than 300 rivers that drain into it.

(C) Siberia's Lake Baikal, with more than 300 rivers draining into it, it holds more of the world's fresh water than all that of the North American Great Lakes combined, 20 percent.

(D) While more than 300 rivers drain into it, Siberia's Lake Baikal holds 20 percent of the world's fresh water, which is more than all the North American Great Lakes combined.

(E) More than all the North American Great Lakes combined, Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.

Look for modifier errors, the modifier should be placed as close as possible to the 'thing' it modifies.

x comma which (x, which) = which will always modify x (as far as I know)

Nothing but A makes sense.

One solution :
with, while - B, D and E can be grouped together and gone.
Split = A : BDE : C = 1:3:1

Another solution :
If you want an answer in 10 secs - look for answer choice that does not have any pronoun - "it". That is A. A has to be the gmat answer bcos writers use a formula to write the credited answer.
