Lignin is a complex substance that makes plants rigid and woody, whereas suberin is the key substance in cork and surrounds plant cells in a thick layer, holding in water during drought.
A. Lignin is a complex substance that makes plants rigid and woody, whereas suberin is the key substance in cork and surrounds plant cells in a thick layer, holding in water during drought.
B. Making plants rigid and woody, while suberin is the key substance in cork, surrounding plant cells in a thick layer and holding in water during drought, lignin is a complex substance.
C. Suberin is the key substance in cork and surrounds plant cells in a thick layer, holding in water during drought, while lignin is a complex substance that makes plants rigid and woody.
D. Whereas suberin is the key substance in cork surrounding plant cells in a thick layer, lLignin is a complex substance that makes plants rigid and woody, holding in water during drought.

Explanation
Choice A: Yes. All modifiers properly refer to their intended subjects and objects, particularly that the thick layer of suberin is holding in water during drought.
Eliminate B because the intro modifier makes no sense with “, while suberin”
Eliminate E for improper semicolon usage. A semicolon must join two independent clauses and may do so with a conjunctive adverb such as however, consequently, or hence. A semicolon may not use a conjunction to join two independent clauses. Whereas is a conjunction.
Then: how to decide between C and D?
We have no way to know whether “holding in water during drought” should modify what suberin/layer does or what lignin/woodiness does.
Option C is the better sentence.
Option D’s main issue exists in this part: “… suberin is the key substance in cork surrounding plant cells in a thick layer.” Surrounding must modify cork, but we’ve got stacked modifiers all over the place and I sense that surrounding should modify suberin.
Option D is hard to understand and its ending modifier is probably not accurate. . . though meaning is impossible to gauge from logic alone.
A woody outer shell (lignin) might hold water in a plant during drought.
A thick layer of some kind of substance (suberin) might also hold water in during a drought.

A. Lignin is a complex substance that makes plants rigid and woody, whereas suberin is the key substance in cork and surrounds plant cells in a thick layer, holding in water during drought. -> Correct.
B. Making plants rigid and woody, while suberin is the key substance in cork, surrounding plant cells in a thick layer and holding in water during drought, lignin is a complex substance. -> comparison between suberin and lignin is done but is not clear. Making...woody -> modifier for lignin are too far apart. Incorrect.
C. Suberin is the key substance in cork and surrounds plant cells in a thick layer, holding in water during drought, while lignin is a complex substance that makes plants rigid and woody. -> and - parallelism indicator - non sensical. Incorrect.
D. Whereas suberin is the key substance in cork surrounding plant cells in a thick layer, lignin is a complex substance that makes plants rigid and woody, holding in water during drought. -> what is holding water -> incorrect meaning. Incorrect.
E. Holding in water during drought, lignin is a complex substance that makes plants rigid and woody; whereas suberin is the key substance in cork, surrounding plant cells in a thick layer. -> suberin helps in holding water -> meaning distorted. Incorrect.
