Question

Match the following \[ \begin{array}{|c|l|c|l|} \hline & List-I & & List-II \hline A & \text{Bioaugmentation} & I & \text{Nutrient addition} B & \text{Biostimulation} & II & \text{Addition of specific microbes} C & \text{Phytoremediation} & III & \text{Use of plants} D & \text{Composting} & IV & \text{Solid waste aerobic treatment} \hline \end{array} \] The correct matching is

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

Hint:

Remember: \[ \boxed{ \begin{aligned} \text{Bioaugmentation} &\rightarrow \text{Add microbes} \text{Biostimulation} &\rightarrow \text{Add nutrients} \text{Phytoremediation} &\rightarrow \text{Use plants} \text{Composting} &\rightarrow \text{Aerobic solid waste treatment} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Recall the definitions. \[ \boxed{ \begin{aligned} \text{Bioaugmentation} &\rightarrow \text{Addition of specific microbes} \text{Biostimulation} &\rightarrow \text{Nutrient addition to stimulate native microbes} \text{Phytoremediation} &\rightarrow \text{Use of plants to remove pollutants} \text{Composting} &\rightarrow \text{Aerobic treatment of solid waste} \end{aligned} } \]

Step 2: Match List-I with List-II. Thus, \[ \boxed{ A-\mathrm{II},\; B-\mathrm{I},\; C-\mathrm{III},\; D-\mathrm{IV} } \] Therefore, \[ \boxed{(A)} \] is the correct answer.
