Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A record failing a validation rule triggered by the DML operation.
Why this is correct
Validation rule failures cause the entire standard DML transaction to roll back.
- ✗
Updating a record that has already been committed in the database.
Why it's wrong here
Updating an existing committed record is a normal valid operation.
- ✗
Using the Database.insert(list, false) method with a failing record.
Why it's wrong here
Passing false allows partial success, meaning valid records succeed while invalid ones fail without rolling back the whole list.
- ✓
Calling record.addError() inside a trigger context.
Why this is correct
addError() rejects the record and aborts the DML operation.
- ✓
Exceeding the maximum heap size limit during processing.
Why this is correct
Hitting governor limits like heap size terminates the transaction with an uncatchable LimitException.
