- Statement I: Rivers and lakes that have low biological productivity are said to be atrophic.
- Statement II: Rivers and lakes that are rich in organisms and organic materials are called oligotrophic.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false ✓ Correct
CStatement I is true but Statement II is false
DStatement I is false but Statement II is true
Correct answer: (B) Both Statement I and Statement II are false — Both statements are false, so the answer is that both Statement I and Statement II are false.
Explanation
★Both statements are false, so the answer is that both Statement I and Statement II are false.
★Waters with low biological productivity are actually called oligotrophic.
★So calling low-productivity waters atrophic is wrong, making statement I false.
★Waters rich in organisms and organic material are actually called eutrophic.
★So calling such rich waters oligotrophic is wrong, making statement II false.
★The two terms have been misapplied in both statements.
★Therefore both statements are false.
