Which ONE of the following options CORRECTLY matches the processes associated with the growth condition given in the table?
$$\begin{array}{|ll|ll|}
\hline & \textbf{Process} & & \textbf{Growth Condition} \\
\hline \text{(P)} & \text{Activated sludge process} & (i) & \text{Anaerobic suspended growth} \\
\hline \text{(Q)} & \text{Anaerobic filter} & (ii) & \text{Anaerobic attached growth} \\
\hline \text{(R)} & \text{Trickling filter} & (iii) & \text{Aerobic suspended growth} \\
\hline \text{(S)} & \text{Anaerobic digestion} & (iv) & \text{Aerobic attached growth} \\
\hline \end{array}$$
- $\text{(P) - (ii); (Q) - (iii); (R) - (iv); (S) - (i)}$
- $\text{(P) - (iii); (Q) - (ii); (R) - (iv); (S) - (i)}$
- $\text{(P) - (iii); (Q) - (i); (R) - (iv); (S) - (ii)}$
- $\text{(P) - (iv); (Q) - (iii); (R) - (ii); (S) - (i)}$
