Why Not Other Options?

References:

Database.insert(records, false):

The Database.insert() method with the allOrNone parameter set to false allows for partial success.

If some records in the list fail due to validation rules, triggers, or other errors, the method will still attempt to insert the remaining valid records.

The false parameter ensures that records that fail will not roll back the transaction for the others.

Why not the other options?

A. Database.insert(records, true):

The true parameter makes the operation transactional (all or none). If any record fails, all records will roll back.

B. insert records:

The insert DML statement behaves like Database.insert(records, true) by default and rolls back all records if any error occurs.

C. insert(records, false):

This syntax is invalid in Apex.

Why WITH SECURITY_ENFORCED?

Ensures field-level security and sharing rules are enforced in SOQL queries.

Prevents unauthorized records or fields from being accessed or displayed.

Why Not Other Options?

B and C: with sharing and inherited sharing enforce record-level access but do not handle field-level security.

D: without sharing ignores sharing rules, which would display all records regardless of user permissions.
