Why each option

To migrate an application's database from SQL Server on an Azure VM to an Azure SQL Database with minimal downtime, transactional replication is the most suitable method.

AImplement log shipping.

Log shipping typically involves restoring transaction log backups, which can lead to significant downtime during the final synchronization and cutover phase, especially for an active online application.

BImplement transactional replication.Correct

Transactional replication enables continuous data synchronization from the source SQL Server database on the VM to the target Azure SQL Database. This allows the application to remain online on the source while the target database is being populated and kept up-to-date, minimizing downtime during the final cutover.

CRestore a BACPAC of the database.
DRestore a backup of the database.
