Before creating a new database collector, you need to perform the following actions:

• Verify the database connection details. You need to provide the host, port, database name, and credentials for the database that you want to monitor. You also need to select the database type and the collector type1
• Create a database user and set user permissions. You need to create a database user with the minimum required permissions to access the database and run the queries that the Database Agent needs. You can use the scripts provided by AppDynamics to create the user and grant the permissions2

To properly configure a database agent from a zip file, you need to provide the following minimum details:

• Controller Host: This is the hostname or IP address of the machine where the Controller is installed. You need to specify this so that the Database Agent can communicate with the Controller and send the collected data1
• Controller Port: This is the port number that the Controller listens on for incoming connections. You need to specify this so that the Database Agent can connect to the Controller using the correct protocol. The default ports are 8090 for HTTP and 8181 for HTTPS for on-premise Controllers, and 80 for HTTP and 443 for HTTPS for SaaS Controllers1
• Account Access Key: This is the key that authenticates the Database Agent with the Controller. You need to specify this so that the Database Agent can register itself with the Controller and access the license. You can find the account access key in the Controller UI under Settings > License > Account1
• Account Name: This is the name of the account that the Database Agent belongs to. You need to specify this so that the Database Agent can associate itself with the correct application and user permissions. You can find the account name in the Controller UI under Settings > License > Account1

When you have a custom dashboard that has only one widget, you can delete that widget by clicking the Delete Widget button on the widget properties panel. This will remove the widget from the dashboard, but it will not delete the dashboard itself. You can still view and edit the dashboard from the Controller UI or the Events Service.

According to the Create and Manage Custom Dashboards and Templates - AppDynamics, when you delete a widget from a custom dashboard, AppDynamics does not create a blank widget because empty dashboards are not allowed. Instead, it preserves the existing widgets on the dashboard and displays them in a single row.

Therefore, B (The widget is deleted, but an empty custom dashboard is maintained) is true. References:
