Comprehensive and Detailed in Depth Explanation:
When a payroll flow task in Oracle Payroll Cloud uses "Bind to Flow Parameter," it retrieves its parameter information from one of the flow pattern parameter values defined at the flow level. These parameters are set when the flow is submitted and provide consistent inputs across tasks. Option A (previous task output) applies to "Bind to Flow Task Parameter," Option B (flow instance context) is not specific enough, and Option D (task parameter values) refers to task-specific settings, not flow-level parameters. This distinction is clarified in the "Payroll Flow Parameters" documentation.
