Answer

Brief Explanations:

Oysters filter water for nutrients, so restoring them would help remove impurities. Option A: Oysters are not top - order consumers, so competition among them won't increase. Option C: Oysters filter sediments, so sediment amount should decrease, not increase. Option D: Filtering by oysters can increase dissolved oxygen (as they help with water clarity and nutrient cycling), so it won't decrease. Option B is correct as filtering improves water quality.

Answer:

B. The water quality of the river ecosystem will improve.
