The sales team has requested that a new field called Current Customer be added to the Accounts object. The default value will be `No` and will change to `Yes` if any related opportunity is successfully closed as won.
What can an administrator do to meet this requirement?
- A. Configure Current Customer as a roll-up summary field that will recalculate whenever an opportunity is won
- B. Use an Apex trigger on the Account object that sets the Current Customer field when an opportunity is won
- C. Use a workflow rule on the Opportunity object that sets the Current Customer field when an opportunity is won
- D. Configure Current Customer as a text field and use an approval process to recalculate its value
