Which of the following is a condition for the termination of a usufruct?

The termination of a usufruct is primarily linked to the death of the usufructuary. A usufruct is a legal right that allows a person to use and enjoy the benefits of someone else's property while preserving its substance. The usufruct is inherently personal; therefore, when the usufructuary dies, the right to that usufruct does not transfer to heirs or successors—it simply ends with their death.

This is important in understanding the nature of usufruct as it highlights the personal aspect of the right; the enjoyment of the property cannot continue beyond the life of the usufructuary.
