Using the rank of classifying organisms from the least in evolutionary trend to the highest:
* People Came For RAMAEC *

People = Porifera
Came = Coelenterata
For = flatworms(platylheminthes)
R = Round worms
A = Annelida
M = Mollusca
A = Arthropoda
E = Echinodermata
C = Chordata

Liver flukes are round worms

Earth worms are Annelids

Snails are Molluscs

Cockroaches are arthropods


Hence coacroach which falls under Arthropoda, is the most advance among them🤲

Liver fluke>>>>Earthworm>>>>Snail>>>Cockroach...

With these points of mine , I think I've convinced you and not confused you that "D" is the right option...

I go for "D" as my final ans

Animals become more advanced in evolution as their body structure, organ systems, and level of organization become more complex.
Liver fluke → Flatworm (very simple body structure).
Earthworm → Segmented worm (more advanced than flatworms).
Snail → Mollusc (more developed organs).
Cockroach → Arthropod (most advanced here, with jointed legs, exoskeleton, and well-developed systems).
