Which endorsement can increase the liability protection in a homeowner's policy?

The personal injury endorsement is designed to enhance a homeowner's insurance policy by providing additional liability coverage specifically for claims related to personal injury. This can include incidents such as defamation, invasion of privacy, and wrongful eviction, which are typically not covered under standard homeowners policies. By adding this endorsement, homeowners can ensure that they have increased protection against these types of liability claims, which can be substantial in nature.

While the other options serve different purposes—such as protecting physical property or adjusting coverage limits—the personal injury endorsement is specifically tailored to expand liability protections, making it the correct answer in the context of the question.
