Pick C. converting S -> CC is equiv to manufacturing its own AF.
D is just wrong ain't it?

A,B,E out -- "its" should be their

between C and D

D distorts the orignal meaning.

in C:

in effect --> means --> in reality/actually

X convert starches into complex carbohydrates called glycerols, <in effect> (reality/actually) manufacturing their own antifreeze

Here it clearly means that... manufacturing referring the earlier process (i.e convert .. Y.. to Z..)

process = manufacturing antifreeze.

This one makesense..

In D.

X convert starches into complex carbohydrates called glycerols, <so that>( consequently/in order that) they manufacture their own antifreeze

it means X converts Y to Z, consequently/in result they manufacture their own antifree.
--> here it says.. they manufacture their own antifreeze.. but we don't know how they manufacture..
It changes the original meaning.

C is the best.
