Which LINQ to Entities query should you use?

A) var query = context.Customers .Where(c => c.MiddleName != null) .Select(c => c.CustomerAddresses.Count();
B) var query = context.Customers .Where(c => c.MiddleName != null) .SelectMany(c => c.CustomerAddresses.Count();
C) var query = context.Addresses .GroupBy(a => a.CustomerAddresses .Where(ca => ca.Customer.MiddleName != null)).Count();
D) var query = context.Addresses .SelectMany(a => a.CustomerAddresses.OfType<Customer>() .Where(c => c.MiddleName != null)).Count();

What should you do?

<asp:Button id="btnUpload" Text="Upload selected file"
OnClick="btnUpload_Click" runat="server" />
<asp:Label id="lblFeedback" runat="server" />

02 {
03 if (...)

ddl.Controls.Add(lbl);
}
