Question

Match the following.

\[ \begin{array}{|c|l|c|l|} \hline \text{List-I} & & \text{List-II} & \\ \hline A & \text{Rise in sea levels} & I & \text{Eutrophication} \\ \hline B & \text{Increase of pollutant at successive trophic levels} & II & \text{Biological oxygen demand} \\ \hline C & \text{Enrichment with nutrients} & III & \text{Greenhouse effect} \\ \hline D & \text{Water hyacinth} & IV & \text{Biomagnification} \\ & & V & \text{Terror of Bengal} \\ \hline \end{array} \]

• A. A--III, B--IV, C--I, D--V
• B. A--III, B--IV, C--II, D--V
• C. A--V, B--I, C--IV, D--III
• D. A--II, B--III, C--I, D--IV

Hint:

Environmental associations: \[ \boxed{ \begin{aligned} &\text{Greenhouse effect} \rightarrow \text{Sea level rise} &\text{Biomagnification} \rightarrow \text{Increase of pollutants in food chain} &\text{Eutrophication} \rightarrow \text{Nutrient enrichment} &\text{Water hyacinth} \rightarrow \text{Terror of Bengal} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Match each item. \[ \begin{aligned} \text{Rise in sea levels} &\rightarrow \text{Greenhouse effect} \text{Increase of pollutant at successive trophic levels} &\rightarrow \text{Biomagnification} \text{Enrichment with nutrients} &\rightarrow \text{Eutrophication} \text{Water hyacinth} &\rightarrow \text{Terror of Bengal} \end{aligned} \] Thus, \[ \boxed{ A-III,\qquad B-IV,\qquad C-I,\qquad D-V } \]

Step 2: Choose the correct option. Hence, \[ \boxed{(A)} \] is the correct answer.
