Answer:
(b) before insurance payouts begin
Explanation:
You want to know when the insurance deductible is paid by the insured.
Deductible
When an insurance claim is made, the amount the insurance company pays out is the amount of the claim (up to the limits of insurance), less the amount of the deductible. Effectively, the deductible is paid before insurance payouts begin.

Additional comment
In practice, the timing of the deductible payment relative to the payment of the claim varies by situation. In the case of a car accident, the repair shop may accept payment from the insurance company, then bill the car owner for the amount of the deductible (and any other costs not covered). That is, the actual payment of the deductible amount may follow after the payment by the insurance company.
For other kinds of claims, the insurance company may write a check to the insured, leaving it to the insured to make up any difference between costs covered by the insurance and the bills for repair or restoration.
