If a property owner and their sibling have a tenants in common ownership arrangement, what occurs when one passes away?

In a tenants in common ownership arrangement, each owner has a specific share of the property, which is not necessarily equal. When one owner passes away, their share of the property does not automatically transfer to the surviving owner, as it would in a joint tenancy. Instead, the deceased owner's share of the property will pass according to their will or, if there is no will, according to the laws of intestacy. This means that the deceased's interest transfers according to the will, not automatically to the co-owner. This is why option C is the correct answer.
