What condition results in a property reverting back to the original owner when a certain event occurs?

The correct answer, which identifies a condition that leads to a property reverting back to the original owner when a certain event occurs, is a condition subsequent.

Essentially, the grant is conditional and ties the ownership of the property to the occurrence of that future event.

For example, a property could be given with the stipulation that it must be used for educational purposes, and if it ceases to be so used, it will revert to the original owner. This concept is distinct from other choices provided, such as a condition precedent, which requires a certain event to occur before the ownership is granted, rather than a condition that can trigger a reversion after the title has been passed.
