The main idea being tested is a complete risk management flow before flight: find hazards, judge how likely they are and how bad their consequences could be, apply controls to reduce the risk, check what risk remains (residual risk), obtain the necessary authorization, and keep monitoring during flight for any changes. This sequence is best because it starts with identifying what could cause harm, then quantifies the risk with both probability and impact, then uses controls to bring that risk down, reassesses to see if the remaining risk is acceptable, secures approval to proceed, and finally maintains vigilance during the operation to catch new or evolving hazards. The other options skip essential steps or put them in an illogical order—for example, moving straight to authorization without analyzing hazards and risk, or omitting the requirement to assess likelihood and consequences—so they don’t reflect a complete, safe, and compliant risk assessment process.
