   A Salesforce admin at a large financial services org has a custom object 'Investment_Account__c' with 500,000 records. A nightly batch job creates Apex managed sharing records for 50,000 new records by iterating through a list and calling Database.insert(shareRecord) inside the loop. The batch job frequently fails with CPU time limit exceeded. Which change would most directly address the CPU limit issue?

   • AUse Database.emptyRecycleBin() before inserting sharing records to free up storage.
   • BReplace Apex managed sharing with manual sharing records created via the UI.
   • CCollect all sharing records in a List and call a single Database.insert(listOfShares) after the loop.
   • DIncrease the batch size from 200 to 2000 to process more records per execution.
