Universal container sales reps can modify fields on an opportunity until it is closed. only the sales operations team can modify the post close follow up date and post close follow up comments fields. how to make this happen ? a. use field-level security on page layouts to restrict editing fields b. use field-level security to mark fields as read=only on the sales profile c. use record types with field sets and restrict editing fields using field-level security d. use multiple record types, page layouts, and profiles

A. Use field-level security on page layouts to restrict editing fields Explanation:

By restricting the field security and access, no undesired changes and editing will occur, in fact people doing false editing will think before doing so, as when there will be field security on editing only the authorized sales person will do so, and not any person in the sales team would think to do so.

Therefore, the modification will only be possible for and when there is actual need and by dignified and authorized personnel.
