- II, IV
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Check each pair.
\[
\text{Nereis} \rightarrow \text{Polychaeta}
\]
Correct.
\[
\text{Pontobdella} \rightarrow \text{Hirudinea}
\]
Hence Statement II is incorrect.
\[
\text{Haemadipsa} \rightarrow \text{Hirudinea}
\]
Correct.
\[
\text{Palaemon} \rightarrow \text{Crustacea}
\]
Correct.
Among the given options the valid combination is:
\[
\boxed{\text{III and IV}}
\]
Hence option (B) is correct.
