Sentence Correction

This is OG 12th ed SC Q133. I was able to narrow down the choices to B and E. However, I did not understand the reasoning provided in OG for the correct answer (B). I have listed my reasoning for incorrect choice (E). Please correct me if I'm wrong.

"To require" in choice (E) does not refer to "laws". Its subject is probably "shrimpers".

------------------------------------------------------------------------------------
Q133. Last week local shrimpers held a news conference to take some credit for the
resurgence of the rare Kemp's ridley turtle, saying that their compliance with laws
requiring that turtle-excluder devices be on shrimp nets protect adult sea turtles.

(B) requiring turtle-excluder devices on shrimp nets is protecting
(E) to require turtle-excluder devices on shrimp nets is protecting
-------------------------------------------------------------------------------------

It comes down to parallelism on this one. To require is not parallel to is protecting.

this is participle vs infinitive

to X - purpose
Xing - details of something


Xing suits here as per the above!

"Requiring" is a modifier, which refers to "the laws."

e.g. He did not want to comply with the law requiring that he change his license plate to a new one.
