A claim is paid by Dennis's household insurers arising out of his liabilities under the Defective Premises Act 1972. The cover provided by his policy is in respect of Dennis being:

The correct answer is that the claim is related to Dennis's liabilities as a former owner of the property. The Defective Premises Act 1972 is designed to impose certain liabilities on those who have an ownership interest in a property, particularly when it concerns the safety of the premises for those who occupy it. Under this Act, former owners can still be held liable for defects that existed during their ownership if those defects lead to injury or damage after they have sold the property.

Dennis's household insurance policy would typically cover liabilities arising from unlawful or dangerous conditions that could affect occupants, even if he is no longer the current owner. This means that if a claim arises from a defect that existed while he owned the property, he can be held liable, and his insurance could respond to that claim, reflecting the ongoing responsibilities of property owners under the Defective Premises Act.

The other options refer to current situations or relationships with the property that would not typically invoke liability under this Act in the same way as ownership does. For instance, a tenant or current occupier may have responsibilities, but these differ from the legal obligations placed on past owners. As a result, the emphasis on past ownership is crucial for understanding the liability framework defined in the Act.
