Final answer:
The dealership must reimburse the customer for the trial period.
Step-by-step explanation:
The correct answer is b) The dealership must reimburse the customer for the trial period.
When a vehicle is mistakenly enrolled in a Uconnect connected services trial period before the sale, the dealership is responsible for reimbursing the customer for the trial period. This is because the customer should not be held responsible for a trial period they did not activate or intend to use.
In this situation, the dealership should rectify the mistake by refunding the customer for the trial period or extending it after the sale is completed.
