https://pupuweb.com/amazon-dea-c01-which-apache-airflow-log-type-should-you-use-to-diagnose-workflow-failures-in-amazon-mwaa/ When a workflow fails to run in Amazon MWAA, the task logs (YourEnvironmentName-Task) are the most relevant for diagnosing the issue. Task logs contain detailed information about the execution of individual tasks within the workflow, including any error messages or stack traces that can help pinpoint the cause of the failure.

Tasks within the workflow but the workflow failed to run from the question. It could be that workflow didn't start at all. I think C is most suitable
