Match the following. 
\[ \begin{array}{|c|l|c|l|} \hline \text{Excretory organs} & & \text{Examples} & \\ \hline \text{A} & \text{Protonephridia} & \text{I} & \text{Terrestrial arthropods} \\ \hline \text{B} & \text{Metanephridia} & \text{II} & \text{Crustaceans} \\ \hline \text{C} & \text{Malpighian tubules} & \text{III} & \text{Larva of annelids} \\ \hline \text{D} & \text{Green glands} & \text{IV} & \text{Cnidarians} \\ \hline & & \text{V} & \text{Annelids} \\ \hline \end{array} \]

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

Hint:

Important excretory organs: \[ \boxed{ \begin{aligned} &\text{Protonephridia} &&\rightarrow \text{Larval annelids / flatworms} &\text{Metanephridia} &&\rightarrow \text{Annelids} &\text{Malpighian tubules} &&\rightarrow \text{Insects} &\text{Green glands} &&\rightarrow \text{Crustaceans} \end{aligned} } \]
