Final answer:
Joint tenancy is the co-ownership that includes 'rights of survivorship,' meaning upon one tenant's death, their share passes to the remaining joint tenants without the need for a will.
Step-by-step explanation:
The type of co-ownership that allows for the tenant's share to automatically pass to the remaining joint tenant(s) upon the tenant's death, known as "rights of survivorship", is c) Joint tenancy. The concept of joint tenancy differs from tenancy in common where each tenant has an individual interest that does not automatically pass to the other tenants upon death. Instead, it can be bequeathed through a will or, if there is no will, it will pass according to state intestacy laws. Joint tenancy owners have equal shares and undivided interest in the property and have the right to the entirety of the property upon the death of a co-tenant.
