What could be the reason for this?

A company stores critical data for a department in Amazon RDS for MySQL DB instances. The department was closed for 3 weeks and notified a database specialist that access to the RDS DB instances should not be granted to anyone during this time. To meet this requirement, the database specialist stopped all the DB instances used by the department but did not select the option to create a snapshot. Before the 3 weeks expired, the database specialist discovered that users could connect to the database successfully.

What could be the reason for this?
A . When stopping the DB instance, the option to create a snapshot should have been selected.
B. When stopping the DB instance, the duration for stopping the DB instance should have been selected.
