One of CATSA's four major areas of responsibility?

• A. Pre-board screening
• B. In-flight meal service quality
• C. Baggage handling operations
• D. Aircraft maintenance oversight

Answer: (A)

CATSA’s responsibility centers on security screening before boarding. The main idea here is that CATSA conducts pre-board screening of passengers and their carry-on items to detect prohibited items and protect air travel. The other options describe activities that are outside CATSA’s security role: in-flight meal quality is a service/operational issue for airlines, baggage handling is managed by airports and airlines, and aircraft maintenance oversight is handled by regulatory bodies like Transport Canada. Because pre-board screening directly matches CATSA’s security screening mandate, it is the correct choice.
