To determine which of the options listed is a free-living parasite, let's analyze each option:

1. **Tapeworm**: This is a type of parasitic flatworm that lives in the intestines of its host. It is not free-living but relies on a host for survival and reproduction.

2. **Planaria**: These are free-living flatworms that can be found in freshwater environments. They are not parasites but rather are known for their regenerative capabilities.

3. **Ascaris**: This refers to Ascaris lumbricoides, a type of roundworm that is parasitic and lives in the intestines of humans. Like the tapeworm, it is not free-living.

4. **Liver fluke**: This type of parasitic flatworm (often belonging to the genus Fasciola) typically resides in the liver of its host. It is also not free-living.

### Conclusion
The only free-living organism in this list is **Planaria**, as the others are all parasitic and depend on hosts for their life cycles.
