A company has a custom object Sales_Help_Request__c that has a Lookup relationship to Opportunity. The Sales_Help_Request__c has a number field, Number_of_Hours__c, that represents the amount of time spent on the Sales_Help_Request__c.

A developer is tasked with creating a field, Total_Hours__c, on Opportunity that should be the sum of all of the Number_of_Hours__c values for the Sales_Help_Request__c records related to that Opportunity.

What should the developer use to implement this?

  • A . A workflow rule on the Sales_Help_Request__c object
  • B . A roll-up summary field on the Opportunity object
  • C . A trigger on the Opportunity object
  • D . A trigger on Sales_Help_Request__c
