Final answer:
The correct answer is 'Access the airline's database.'
Step-by-step explanation:
The correct answer is b) Access the airline's database. If you want to find your DRQs (Disruption Recovery Queue) and resolved ones, you would need to access the airline's database. The airline's database contains information about flight disruptions, including the DRQs and their status.
If you choose option a) Ask the passengers directly, they may not have access to the necessary information. Option c) Consult the flight crew may not be feasible as the flight crew might not have access to the database. Option d) Call the airline's customer service can be helpful, but it is more efficient to access the airline's database directly.
