Explanation

The correct answer is B: Map table columns from the parent record to the child record. In Dynamics 365 and Power Apps model-driven apps, relationship column mappings (configured under the relationship definition) allow you to specify that when a child record is created from a parent record's subgrid, certain parent field values are automatically copied into the corresponding child record fields. This is a native, no-code platform feature that fulfills the requirement of auto-populating child record data to reduce input errors. A Power Automate flow (A) would fire after the record is created, not at form open time, so the fields wouldn't pre-populate before saving. A business rule (C) can set default values but cannot dynamically pull values from a specific parent record without custom scripting. A quick view form (D) displays parent data on the child form read-only but does not populate editable child fields.
