In Many Parts of the Everglades in Florida,excessive Irrigation Is

In many parts of the Everglades in Florida,excessive irrigation is lowering water levels and allowing salt water to enter the normally freshwater swamps.Why is this a problem for plants that have adapted to life in these swamps?

A) The salt competes with minerals for uptake by the plants, limiting their growth
B) Salts bind to nitrogen, preventing it from being taken up
C) The plants cannot move sugars down the xylem if there is salt outside of the roots pulling water out
D) Photosynthesis is inhibited by salt
E) The plant roots cannot take up water if the soil salt concentration is high
