You are developing an ASP.NET MVC application. The application is an order processing system that uses
the ADO.NET Entity Framework against a SQL Server database. It has a controller that loads a page that
displays customers. Customers are filtered on Country and, if provided, on CompanyName.
You have an Entity Framework context named db.
The Customer class is shown below.
You need to execute a single deferred query to return the filtered list of customers.
Which code segment should you use?
