Oligotrophic water bodies are characterised by low nutrient content and low productivity. These water bodies have low levels of biological activity and low levels of organic matter. As a result, the biological oxygen demand is low and the dissolved oxygen levels are high. 

Option 1 is incorrect because oligotrophic water bodies have low nutrient content.

Option 2 is incorrect because oligotrophic water bodies have low levels of organic matter and low biological oxygen demand.
