Connection Strings

This is not an exam or homework

You have created the following connection string entry in the web.config:
<connectionStrings>
<add name="TestConnectionString" connectionString="Data Source=Test;Datbase=Test;UID=google;Password=google" providerName="System.Data.SQLClient"/>
<connectionStrings>

Which of the following code segments reads the connection string information from the web.config and assigns it to a SQLConnection object?

1.
Imports System.Configuration
Imports System.Data.SqlClient
...
Dim con As New SqlConnection
con.ConnectionString = ConfigurationManager.ConnectionStrings("TestConnectionString")
 
2.
Imports System.Configuration
Imports System.Data.SqlClient
...
Dim con As New SqlConnection
con.ConnectionString = ConfigurationManager.RetrieveConnectionString("TestConnectionString")
 
3.
Imports System.Configuration
Imports System.Data.SqlClient
...
Dim con As New SqlConnection
con.ConnectionString = ConfigurationManager.GetConnectionString("TestConnectionString")
 
4.
Imports System.Configuration
Imports System.Data.SqlClient
...
Dim con As New SqlConnection
con.ConnectionString = ConfigurationManager.ConnectionStrings("TestConnectionString").ConnectionString
