Universal Containers has a custom object that holds over 100 fields.

The "Accordion" Lightning component is designed to break up content into collapsible sections. This component would be suitable for managing the visibility of large numbers of fields by grouping them into separate tabs or sections that can expand and collapse. This makes navigation easier and declutters the interface.

A: Highlights panel is used for displaying key record information at the top of the page and is not designed for managing multiple fields.

B: Record detail displays all fields on a single layout, which does not suit the requirement to break up the fields.

C: Field section does not exist as a standard Lightning component. Reference: Accordion Component in the Lightning Component Library
