Option A: Create a Custom Permission for the users.
True.
Custom Permissions can be used to control access to specific functionality.
By assigning the custom permission to a small group of users, the form's availability is restricted.
A Lightning Web Component can be built to display the form and handle dynamic field display based on the user's job role.
Dynamic Forms allow fields to be displayed or hidden based on criteria, such as user role.
Dynamic Actions control button visibility, not form fields.
Option D: Add a Dynamic Action to the Users' assigned Page Layouts.
Not Necessary.
Page Layouts are less flexible for controlling field-level visibility based on user role compared to Dynamic Forms.
Conclusion:
The three things the developer should do are A, B, and E.
