When an assignment is only in Draft status, which option is not available?

When an assignment is in Draft status, it indicates that the work is still in progress and has not yet reached a finalized state. In this context, deletion is not available because a draft document is typically seen as a work-in-progress that may still need to be reviewed, modified, or potentially finalized later. The implication is that deleting a draft may not be a standard operation since it would mean discarding potentially valuable content that could still be useful in the development of the assignment.

Revocation, finalization, and modification are actions that can be performed on drafts. Revocation could involve withdrawing the draft from consideration while still allowing for modifications. Finalization involves completing the assignment, transforming it from draft status to a completed document. Modification allows the author to make changes to the draft as necessary. Therefore, these actions are applicable to a draft, while deletion stands out as an option that is not typically available until the assignment has reached a more final state.
