Which of the following is a criterion for determining authorship?

Final approval of the version is a key criterion for determining authorship because it signifies that the individual took responsibility for the content of the work and agrees with its final form. This approval indicates that the authors have not only contributed to the research but have also engaged with the manuscript to ensure accuracy and clarity. Authorship typically involves significant intellectual contribution, and agreeing to the version being published reflects a commitment to the integrity of the work.

In the context of research and publication ethics, the act of providing final approval shows that the author has reviewed the work comprehensively and endorses the findings, methodology, and conclusions presented. This criterion ensures accountability and maintains the standards of scholarly communication.
