Amphiprotic species are those species that can act as both an acid and a base. They can donate or accept a proton depending on the reaction conditions.

Species and their properties:

I: HPO32-
- Can act as an acid by donating a proton to a base
- Can act as a base by accepting a proton from an acid

II: OH-
- Can act as a base by accepting a proton from an acid
- Cannot act as an acid

III: H2PO4-
- Can act as an acid by donating a proton to a base
- Can act as a base by accepting a proton from an acid

IV: HCO3-
- Can act as an acid by donating a proton to a base
- Can act as a base by accepting a proton from an acid

Answer:
Based on the above properties, the amphiprotic species are III (H2PO4-) and IV (HCO3-), therefore the correct answer is option C.
