Correct Answer – B
Amazon SQS FIFO queues use message group ID for orderly delivery of messages.
Option A is incorrect as Batch ID is an invalid option.
Option C is incorrect as this is used for the deduplication of messages & not for the orderly processing of messages.
Option D is incorrect as the Sequence number is a unique number assigned by AWS SQS & this will not impact the order of messages.
