Answer:
B- The speed of sound will increase due to the increasing density of seawater.

The correct answer is A.
Water runoffs usually carry nutrients especially fertilizers from off the landscape and washed them into the wetlands and other water bodies. Phosphorus is a common ingredient that is present in all fertilizers. Phosphorus acts as a pollutant in these water bodies and put the organisms living in the water bodies at risk. High concentration of phosphorus causes rapid growth of plants in the wetlands and lead to depletion of oxygen leading to the death of organisms living in the wetlands.
Due to this occurrence, the Florida government has taken steps and enact several laws to ensure that the phosphorus pollution is arrested in order to preserve the wetlands.
