Explanation:

River mouths are transition zones between rivers and larger water - bodies. They are rich in nutrients from the river flow, which support a wide variety of species, leading to increased species diversity. Water is often turbid due to sediment load, oxygen levels can vary but are not necessarily low, and vegetation levels are not always high.

C. increased species diversity
