   A team wants to automatically retrain a model every time a new dataset is uploaded to an S3 bucket. They have set up an EventBridge rule that triggers a SageMaker training job when an S3 object is created. The training job starts, but the team notices that the training job sometimes fails because the dataset is still being uploaded when the job starts. What should the team do to ensure the training job only starts after the upload is complete?

   • AUse a Step Functions state machine that waits for the S3 object to be fully written before starting the training job.
   • BIncrease the training job's timeout so it can handle partial uploads.
   • CConfigure the EventBridge rule to use a custom event pattern that only matches when the S3 object is fully written.
   • DUse S3 event notifications with a suffix filter and configure the training job to wait for the object to be fully written.
