Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

To map the department field only if source department is not empty.

The transform script maps the 'department' field only if the source field 'u_department' is not empty, as indicated by the conditional logic. Option A is incorrect because the script does not ignore records; it only skips mapping for empty departments. Option C is incorrect because no default value is set; the field is simply not mapped if empty. Option D is incorrect because only the department field is mapped conditionally, not all fields.
