Final Answer :
B
Explanation :
The pseudocoelom has evolved independently in different animal taxa, making it an example of convergent evolution rather than a shared ancestral trait. This means it is not a reliable characteristic for determining evolutionary relationships or phylogeny among different groups of animals.
