What has been the greatest environmental impact as a result of the tsunami?

a. the destruction of mangroves and coral reefs

b. the infiltration of salt water and drinking supplies and farmland

c. destruction of sewage collectors and water treatment plants

d. severe damage done to sand dunes and rock formations

b. The infiltration of salt water and drinking supplies and farmland

Explanation:

Although all the options are valid in relation to the damages caused by a tsunami, these damages are part of the natural cycle that marine and coastal life faces. However, the filtration of salt water affects the terrestrial ecosystem by contaminating vital aquifers for many terrestrial animals, and also for humans, creating a greater environmental impact.

Also, contamination with salt from farmland leads to a decrease in local cultivation and fertile land around coastal areas.
