The following table gives various components of Municipal Solid Waste (MSW) and a list of treatment/separation techniques.
\begin{array}{|l|l|}
\hline \text{Component of MSW} & \text{Treatment/separation technique} \\
\hline \text{P - Ferrous metals} & \text{i - Incineration} \\
\text{Q - Aluminum and copper} & \text{ii - Rapid composting} \\
\text{R - Food waste} & \text{iii - Eddy current separator} \\
\text{S - Cardboard} & \text{iv - Magnetic separator} \\
\hline
\end{array}
The CORRECT match is
- $\text{P-iii, Q-iv, R-i, S-ii}$
- $\text{P-iv, Q-iii, R-ii, S-i}$
- $\text{P-iii, Q-iv, R-ii, S-i}$
- $\text{P-iv, Q-iii, R-i, S-ii}$
