Final answer:
Christopher would likely need Theft: special form coverage under his DP-3 policy to ensure his belongings are covered for theft while traveling abroad. The DP-3 policy is a Special Form policy that provides broad coverage for the dwelling and named perils for personal property, which can include theft, but specifics depend on his policy's terms.
Step-by-step explanation:
The DP-3 policy is known as the Special Form homeowners insurance policy for rental properties, which is the most comprehensive of the Dwelling policy forms. It typically provides coverage on an open perils basis for the dwelling itself, meaning it covers all causes of loss not specifically excluded in the policy. When it comes to personal property, such as Christopher's belongings, the DP-3 policy usually includes coverage for named perils, including theft. However, additional coverage may be necessary for theft outside the home, such as when traveling.
To be protected against theft while traveling, Christopher would need a policy that includes Theft: broad form coverage or an endorsement that provides coverage for personal property while it is off the premises. There isn't a specific option listed as Theft: abroad form; rather, coverage for personal property while traveling would generally be considered under the broader protection of the policy, possibly with a special endorsement for off-premises theft.
Therefore, the answer to which additional coverage Christopher would need under a DP-3 policy to be covered for theft abroad is likely A. Theft: special form. This is the option that aligns with the comprehensive nature of the DP-3 policy and the broad personal property coverage that Christopher would require while traveling.
