Final answer:
Janet should purchase liability insurance to cover potential legal costs and payouts for negligence and innocent mistakes in her role as a property manager.
Step-by-step explanation:
Janet, as a property manager interested in protecting herself from the financial consequences of her professional negligence and innocent mistakes, should consider purchasing liability insurance. This type of insurance is specifically designed to cover legal costs and any resulting payouts for which the insured individual or business can be held legally liable. For instance, if a tenant were to sue Janet for negligence resulting in property damage or personal injury, her liability insurance would likely cover the associated costs.
Property insurance is generally intended to protect physical assets against damage from events like fire, theft, or natural disasters. Renters insurance is typically purchased by tenants to protect their personal property inside a rented space, and title insurance provides protection against disputes over property ownership. Therefore, the correct answer in this scenario is b) Liability insurance.
