AFleas (Tunga Penetrans)
BFruit flies (Diptera, Tephritidae)
CApple snails (Pomacea lineata)
DMosquitoes (Aedes Aegypti)

Correct Option: 3  

Explanation:
Apple snails (Pomacea lineata)
The Pantanal is a large system of wetlands, which floods annually. During and after the flood there are deep layers of decomposing matter, and the Apple Snails which have both gills and lungs (and a long snorkel), can thrive in the anoxic waters and deal with recycling the dead plants.
