Which of the following describes an estate that can be created through a conveyance with conditions?

A fee simple determinable is an estate that is created through a conveyance where the property is transferred with specific conditions attached. This type of estate automatically terminates if the conditions specified in the conveyance are not met or fulfilled in the future. The future interest in the property reverts back to the grantor or their heirs.

For example, if a property is conveyed "to John, as long as the property is used for educational purposes," the estate would be a fee simple determinable. If the property were to be used for anything other than educational purposes, the condition is breached, and ownership would automatically revert to the original owner.

Other types of estates listed do not involve such conditional terms. For instance, a fee simple absolute grants complete ownership without conditions or limitations. A life estate lasts for the duration of someone's life and does not include conditional terms tied to the ownership. A leasehold estate is an agreement that grants the right to use the property for a specified period but does not hold the same kind of conditional future interest characteristic of a fee simple determinable.
