Which alternative contains a clause from the passage in the active voice?

The ABSTRACT is not a part of the body of the report itself. Rather, the abstract is a brief suramary of the report contents that is often separately circulated so potential readers can decide whether to read the report. The abstract should very concisely summarize the whole report: why it was written, what was discovered or developed, and what is claimed to be the significance of the effort. The abstract does not include figures or tables, and only the most significant numerical values or results should be given.
