Scientists predict that the next large hurricane to strike the Gulf coast will have unimaginably catastrophic results, including a total breakdown of the levee system, infiltration and contamination of the Mississippi River by salt water, permanently altering the coastline and completely destroying New Orleans' wetlands.

Choices

A permanently altering the coastline and completely destroying

B causing permanent alterations to the coastline, and completely destroying

C altering the coastline permanently from its current form, and complete destruction of

D permanent alterations to the coastline, and complete destruction of

E permanent alterations to the coastline's form, and complete destruction in

D is correct.

A, B and C are incorrect because of parallelism error. Since we have total breakdown of the levee system and infiltration and contamination of the Mississippi River by salt water, so we cannot select the options which have words that end with "ing".

Hope this is the correct answer!
