No one should be allowed to edit issues in a particular workflow status of a...

Okay, let's analyze this question again with the revised options.

The requirement is to preventanyonefromeditingan issue when it resides in aspecific workflow status.

As established previously:

Conditions (A):Control whether atransitionout of or into a status can occur. They check criteriabeforea transition starts. They don't prevent editingwhilean issue is sitting in a status.

Post Functions (Implied by B & C):Actions that executeaftera transition is successfully completed (e.g., updating a field, sending a notification). They don't affect editability within the status itself.

Triggers (D):Automatically initiate a workflow transition based on external events (like code commits). Not relevant to editing permissions within a status.

The correct way to achieve this in Jira is by setting aStatus Property:

Navigate to Workflow configuration.

Select the relevant status.

Go to its 'Properties'.

Add a property: jira.issue.editable with the value false.
