1. Adobe Workfront Documentation - Associate tasks with milestones: This document explicitly details the two primary methods.
For In-line Editing (A): Under the section "Associate a task with a milestone in a list
" it states
"You can associate a task with a milestone when editing it in a list of tasks... Add the Milestone column to your task view. Click the Milestone column for the task you want to associate with a milestone
then start typing the name of the milestone."
For Bulk-Editing (C): Under the same section
it describes the bulk edit process: "Select multiple tasks in a task list... Click the Edit icon... In the Edit Tasks box that displays
scroll to the Milestone field and start typing the name of the milestone."
2. Adobe Workfront Documentation - Edit tasks: This document clarifies the different editing areas for a task. The "Milestone" field is located in the "Task Details" section of the Edit Task dialog box
not in the "Settings" section
confirming why option D is incorrect.
3. Adobe Workfront Documentation - Milestone view: This source confirms the purpose of the Milestone View. It states
"The Milestone view provides a simple
easy-to-read
visual representation of the milestone path on your project
" confirming it is for visualization
not for editing task associations
which makes option B incorrect.
