In Adobe Real-Time Customer Data Platform, selecting the right segmentation method depends on the complexity of the logic and the required lookback duration.

Rule-Based Segments (Option A)are the standard way to build audiences in theSegment Builder. They allow data analysts to drag and drop various attributes and events, using boolean logic (AND/OR/NOT) to create highly specific filters. This is the primary method for handling "complex conditions" involving multiple profile traits and behavioral events.

Batch Evaluation Segments (Option D)are specifically recommended when those complex expressions involvelong lookback windows(e.g., "purchased in the last 18 months") or require processing massive historical datasets that exceed the limits of the streaming engine. Batch segmentation runs on a scheduled basis (usually once every 24 hours) and performs a full scan of the Real-Time Customer Profile store, making it the most robust choice for high-complexity calculations that do not require millisecond-level updates.

Option B is incorrect as "Audience Export" is an activation step, not a creation method. Option C,Computed Attributes, are useful for simplifying segments (e.g., calculating a "Total Lifetime Value"), but they are a data preparation tool rather than a segmentation method itself. Using a combination of Rule-Based logic evaluated via the Batch engine provides the analyst with the most powerful toolkit for complex filtering.
