But wouldn't setting the maximum concurrency limit of the Lambda function to 1 be a more cost-effective solution?

Option A seems like the easiest solution, but I'm not sure if it's the most cost-effective. FIFO queues can be more expensive than standard queues.

I disagree, setting up a dead-letter queue could also help in resolving the issue.

I think the best option is to change the Amazon SQS standard queue to an Amazon SQS FIFO queue.
