Concept:Freehold tenure grants the holder full legal ownership of land, allowing the outright purchase and sale of the property.
Explanation:The question asks which land tenure system involves the outright purchase of land.
Outright purchase means the buyer obtains permanent and absolute ownership over the land.
This is exactly what freehold tenure provides.
In freehold, the owner has the right to use, sell, or transfer the land without restrictions from a landlord or the community.
Leasehold only gives temporary rights through a lease agreement.
Communal land is owned by the community as a whole.
Inheritance refers to land passed down after a person's death.
None of these involve an outright purchase.
Hence, freehold is the only system that matches the description.
Answer:C. freehold
