You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET. The application connects to a Microsoft SQL Server 2005 database.

You need to separate the security-related exceptions from the other exceptions for database operations at run time.

Which code segment should you use?

A.
catch (System.Security.SecurityException ex)
{
//Handle all database security related exceptions.
}

B.
catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++)
{
if (ex.Errors[i].Class.ToString() == "14")
{
//Handle all database security related exceptions.
}
else
{
//Handle other exceptions
}
}
}

C.
catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++)
{
if (ex.Errors[i].Number == 14)
{
//Handle all database security related exceptions.
}
else
{
//Handle other exceptions
}
}
}

D.
catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++)
{
if (ex.Errors[i].Message.Contains("Security"))
{
//Handle all database security related exceptions.
}
else
{
//Handle other exceptions
}
}
}
