Explanation

Inline discovery places a sensor or device directly in the network traffic path, meaning all data flows through it - this makes it ideal for impact assessment because it captures a complete, real-time picture of what is traversing the network segment. Passive discovery (A) only observes traffic that happens to reach the sensor from a mirrored port or tap, so it may miss traffic on other segments and is better suited for reconnaissance without disruption. Statistical analysis (B) and heuristic analysis (D) are analysis techniques applied to already-collected data, not discovery methods - they describe how you interpret findings, not how you find them. A useful memory anchor: "inline = in the line" - the tool sits directly in the traffic flow, so nothing passes without being seen, which is exactly what a thorough impact assessment requires.
