Why each option

The Apex `merge` operation supports specific standard objects like Accounts, Contacts, Cases, and Leads, and allows merging up to three records into a single master record.

AThe field values on the master record are overwritten by the records being merged.

When merging records, the field values of the *master* record are typically retained and generally take precedence over those of the records being merged, meaning they are not overwritten by the duplicate records.

BMerge is supported with accounts, contacts, cases, and leads.Correct

The DML `merge` operation in Apex is specifically designed and supported for standard objects that commonly require deduplication, including Account, Contact, Lead, and Case.

CExternal ID fields can be used with the merge method.

External ID fields cannot be directly used with the `merge` method to identify records for merging; the `merge` operation relies on Salesforce record IDs.

DThe merge method allows up to three records, including the master and two additional recordsCorrect

The `merge` DML statement enables the consolidation of records by allowing one master record to absorb up to two additional duplicate records, combining their related lists and typically retaining the master's field values.
