Given below are two statements, one is labelled as Statement I and the other is labelled as Statement II.
Statement I: The nutrient deficient water bodies lead to eutrophication.
Statement II: Eutrophication leads to decrease in the level of oxygen in the water bodies.
In the light of the above statements, choose the most appropriate answer from the options given below:
- Option A:
Both statement I and statement Il are incorrect.

Step-by-step solution
Statement I is Incorrect: Eutrophication occurs due to nutrient-rich (not nutrient-deficient) water bodies, mainly excess nitrates and phosphates.
Statement II is Correct: Eutrophication causes excessive algal growth and decomposition of biomass reduces dissolved oxygen in water.
Thus, Statement I is incorrect and statement Il is correct..
