You are implementing a WCF Data Service to expose data from a database named Northwind.
You create a class named NorthwindDataService that extends DataService. You add the following method:

public static void InitializeService(IDataServiceConfiguration config)
{
}

You need to ensure that client applications can read Customers entities and cannot access Products and Orders entities.

Which code segment should you add to the InitializeService method?

The SetEntitySetAccessRule method sets the access rules for the specified entity set. The default configuration is to deny access to resources. When a service is initialized, the access rights must be enabled. To enable access to the Customers entities, call this method with the EntitySetRights.AllRead access. You do not need to deny access to the Products and Orders entities because it is denied by default.

The SetServiceOperationAccessRule method sets the access rules for the specified service operation.
