If I have multiple Read Replicas for my master DB Instance and I promote one of them, what happens to the
rest of the Read Replicas?

A.
The remaining Read Replicas will still replicate from the older master DB Instance

B.
The remaining Read Replicas will be deleted

C.
The remaining Read Replicas will be combined to one read replica

Explanation:
If a source DB instance has several Read Replicas, promoting one of the Read Replicas to a DB instance has
no effect on the other replicas.
