Types of flood routing and methods are given in the table below.
\[
\begin{array}{|l|l|}
\hline
\begin{array}{l}
\text{Column 1}\\
\text{Type of Flood Routing}
\end{array}
&
\begin{array}{l}
\text{Column 2}\\
\text{Method}
\end{array}
\\
\hline
\begin{array}{l}
(P)\ \text{Hydrologic routing}\\
(Q)\ \text{Hydraulic routing}\\
(R)\ \text{Reservoir routing}\\
(S)\ \text{Channel routing}
\end{array}
&
\begin{array}{l}
(i)\ \text{Muskingum method}\\
(ii)\ \text{Modified Pul's method}\\
(iii)\ \text{Method of Characteristics}
\end{array}
\\
\hline
\end{array}
\]
Option(s) giving the CORRECT match(es) between Column $1$ and Column $2$ is/are:
- $(\mathrm{P})-(\mathrm{i}) ;(\mathrm{Q})-(\mathrm{iii}) ;(\mathrm{R})-(\mathrm{ii})$
- $(\mathrm{Q})-(\mathrm{i}) ;(\mathrm{R})-(\mathrm{iii}) ;(\mathrm{S})-(\mathrm{ii})$
- $(\mathrm{P})-(\mathrm{i}) ;(\mathrm{R})-(\mathrm{ii}) ;(\mathrm{S})-(\mathrm{i})$
- $(\mathrm{P})-(\mathrm{ii}) ;(\mathrm{Q})-(\mathrm{iii}) ;(\mathrm{R})-(\mathrm{ii})$
