<reasoning>

Match biogeographic realms to geographic regions

• South America corresponds to the Neotropic realm.
• North America corresponds to the Nearctic realm.
• Oceania corresponds to the Oceanian realm (not listed in the draggable options, but Indomalaya is adjacent/relevant; however, looking at standard biogeographic matches: Africa matches Afrotropic, South America matches Neotropic, North America matches Nearctic. This leaves Oceania to match the remaining option, Indomalaya, which is often grouped or adjacent in simplified regional biogeography exercises).
• Africa corresponds to the Afrotropic realm.

<answer>

Region	Biogeographic Realm
North America	Nearctic
Oceania	Indomalaya
Africa	Afrotropic
