Which of the following is a leasehold estate of indefinite duration?

A tenancy in common refers to a form of joint ownership where two or more individuals hold title to a property. Each tenant has a distinct, undivided interest in the property, which does not specify a duration for possession. However, it is not a leasehold estate and thus does not meet the criteria of having a defined or indefinite duration related to tenancy.

This ownership arrangement allows co-owners to inherit each other's interests upon death, ensuring that the property passes to the remaining tenants. Like tenancy in common, it pertains to ownership rather than a leasehold estate and is typically characterized by its survivorship feature rather than duration.

This is a form of joint ownership available only to married couples, where both spouses hold equal interest in the property. It also includes rights of survivorship but is a fixed form of ownership rather than a leasehold estate with indefinite duration.
