To answer this question, you need to understand how a defect management system keeps track of changes made to a defect.
Let's go through each option to understand why it is correct or incorrect:
Option A) Audit tab in the Defect module - This option is incorrect. The audit tab typically contains information about who made changes to the defect, when the changes were made, and what changes were made. However, it does not provide a detailed trail of the changes made to the defect.
Option B) Status column in defect grid - This option is incorrect. The status column in the defect grid usually displays the current status of the defect (e.g., open, in progress, closed), but it does not provide an audit trail of the changes made to the defect.
Option C) History tab in the Defect module - This option is correct. The history tab in the defect module is where you can find an audit trail of the changes made to the defect. It typically displays a chronological list of all the changes made to the defect, including the date, time, and details of each change.
Option D) Summary column in the Defect grid - This option is incorrect. The summary column in the defect grid usually displays a brief summary or description of the defect, but it does not provide an audit trail of the changes made to the defect.
The correct answer is C) History tab in the Defect module. This option is correct because the history tab is specifically designed to provide an audit trail of the changes made to a defect.
