Under which coverage part is the Loss Payee paid jointly with the insured?

The correct answer is Part D. In a Personal Auto Policy, Part D specifically addresses coverage for damage to your vehicle, including physical damage coverage such as Collision and Other Than Collision (Comprehensive). Under this part of the policy, if there is a loss to a vehicle that is financed and a Loss Payee is named on the policy, the Loss Payee will be paid jointly with the insured in the event of a covered loss. This ensures that both the insurer's obligation to pay for damages and the interest of the lender or leasing company are protected.

The other parts of the Personal Auto Policy serve different purposes. For instance, Part A deals with Liability coverage, Part B addresses Medical Payments coverage, and Part C focuses on Uninsured/Underinsured Motorist coverage. None of these parts would involve the payment process for physical damage to the vehicle in the context of a named Loss Payee. Therefore, it's clear that Part D is specifically designed for circumstances that involve paying a Loss Payee alongside the insured in loss situations.
