What is the risk of increasing max.in.flight.requests.per.connection while also enabling retries in a producer?

The correct answer is B. Message order not preserved. Some messages may require multiple retries. If there are more than 1 requests in flight, it may result in messages received out of order. Note an exception to this rule is if you enable the producer settingenable.idempotence=true which takes care of the out of ordering case on it
