✓
The user 'sapadmin' stopped the instance i-0abcdef1234567890.
The eventName is StopInstances and the user is sapadmin, meaning the user successfully stopped instance i-0abcdef1234567890. Options A and B are incorrect: A is wrong because there is no error code, indicating the API call succeeded; B is wrong because the eventName is StopInstances, not StartInstances. Option D is wrong because the eventSource is ec2.amazonaws.com, indicating an EC2 instance, not an RDS instance.
