   A developer is designing an API for a custom table that tracks equipment maintenance. External systems need to perform two operations: (1) mark a specific equipment record as 'in maintenance' and (2) run a bulk process that updates the maintenance status for all equipment that is overdue. The developer wants to expose both operations through the same API. What should the developer do?

   • AAdd a bound action to the equipment API page for the single-record update, and add an unbound action to the same page for the bulk process.
   • BCreate a separate API page for the bulk process and add a bound action to the equipment page for the single-record update.
   • CUse an unbound action for the single-record update and a bound action for the bulk process.
   • DAdd two bound actions to the equipment API page: one for the single-record update and one for the bulk process.
