Answer is C.If Database.insert()'s twice parametar is false,It does not throw an error when insert workin is fail.Therefore, in this situation, it is more appropriate to directly access the SaveResult array rather than using try-catch.

I will go with B. Since multiple accounts are inserted. Option D is correct if it is - 'Collect the insert method return value a List<Database.SaveResult> record'. Single record is an illegal assignment. Hope it helps!

we can also do this using try/catch, and get the error message debugged.

because we have Database.insert(a, false); so this method will be pass in Database all the succeed records and with the Saveresult record we are fetching the errors and the success from all the inserts that Database.insert(a,false) try to proceed

Why is the answer C and not B, can someone explain please.
