An event log is the foundation of Process Mining, providing the raw data needed to reconstruct process flows. The SAP Signavio documentation specifies the mandatory components of an event log:

Option B (Unique Case ID):A unique identifier for each process instance (case) is essential to track individual process executions and correlate events within the same case.

Option D (Timestamp):Timestamps indicate when each event occurred, enabling the sequencing of activities and calculation of metrics like cycle time or delays.

Option E (Activity name):The name of each activity (e.g., "Order Created") describes the specific action performed, allowing Process Mining to map out the process flow.

Option A (Customer ID)is incorrect as it is an optional attribute, not a mandatory component of an event log, though it may be included for specific analyses.
