The media recovery will fail because you have performed a RESETLOGS to recover from the corruption and you have not taken another backup after the RESETLOGS operation.
B. The media recovery will be successful because you can perform a RESETLOGS torecover from an incomplete recovery to a new point-in-time greater than the RESETLOGS operation.
