Answer: c.) Either A or B.
Step-by-step explanation:
If the other driver’s insurance company acknowledges that the accident was caused by that other driver, then they have to pay for the repairs. If they don´t, the case could go to trial.
Furthermore, in many cases, your insurance will fix your car and seek restitution from the at-fault coverage.
Especially when both drivers have insurance, it is better to claim from the insurance of the driver at-fault, to avoid paying any deductibles or out of pocket costs.
