A Correct answer
Explanation

Octopuses have three hearts - two branchial hearts pump blood through the gills, and one systemic heart circulates blood to the rest of the body. This adaptation helps them meet the high oxygen demands of their active lifestyle. Starfish, snails, and sting rays do not have multiple hearts.
