The correct answer is C. Page header section.
A report header section is a section of a report that appears at the top of each page of the report. It typically includes the report title, the date, and the page number.
A summary section is a section of a report that provides a brief overview of the report’s contents. It typically includes the report’s purpose, scope, and findings.
A details section is a section of a report that provides detailed information about the report’s findings. It typically includes tables, graphs, and other visuals.
A page header section is not a report section because it does not provide any information about the report’s contents. It is simply a decorative element that appears at the top of each page of the report.
