The correct option is
D persuade the reader to do something
Options A, B and C: A report is written to convey information about a particular topic. Hence, it must be based on facts.
While reporting an event, it must lay out information on that event, by stating what happened and other importance details covering that event.
These options, hence, state things that should be done. The question asks for the option that should not be done while writing a report.
Hence options A, B and C are wrong.
Option D: A report should not be persuasive, but merely informative.
Hence option D is correct.
