Final Answer :
B
Explanation :
A lake that is rich in algae and rooted plants but lacks oxygen is considered eutrophic. This is because eutrophic lakes have high nutrient levels, such as nitrogen and phosphorus, which can promote the growth of plants and algae. However, as these plants die and decompose, they can consume large amounts of oxygen, leading to low oxygen levels in the water.
