Final answer:
In academic journal formats, the preliminary part of a thesis or dissertation generally includes institution-required items like informed consent forms, but such materials are omitted for publication submissions.
Step-by-step explanation:
In the journal format for theses and dissertations, the preliminary part contains materials that are typically required by the institution, such as an informed consent form for experiments. A journal-style thesis incorporates one or more chapters in a format suitable for publication (but not necessarily published) in a peer-reviewed title, with a supporting commentary.
Examples of suitable formats include journal papers, book chapters, or any discipline-specific alternatives.This section often includes materials that are left off when submitting the study for publication, making the correct answer e. only a and b. The inclusion of informed consent forms is particularly critical as it signifies the participants' voluntary participation and understanding of the research study's potential risks and confidentiality of their data.
