Which of the Following Represents an Audit Trail

Which of the following represents an audit trail?

A) A team of researchers keeps a detailed recollection of their research process, including participant recruitment materials, focus group guides, transcribed focus groups (with changes from member checks) , data analysis materials (e.g., code book and detailed process) , and emergent themes. Someone external to the team reviews these materials to look for any problems or issues.
B) A researcher engages in an armchair walkthrough to help plan a coherent study.
C) When researchers have some expectation about the performance of participants and are in a position to assess performance, their knowledge of the study could influence their judgment on the way they respond to participants. This may lead to coercing the participants.
D) A researcher maintains prolonged engagement with participants to enhance the quality of the research. Sustained time at the research site can help participants feel more natural in the presence of the researcher, while also allowing researchers to check their own perceptions.
