You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve order information from a Microsoft SQL Server database. The application includes the following code. (Line numbers are included for reference only.)
The application must meet the following requirements:
. Return only orders that have an OrderDate value other than null.
. Return only orders that were placed in the year specified in the OrderDate property or in a later year.
You need to ensure that the application meets the requirements.
Which code segment should you insert at line 08?
A. Where order.OrderDate.Value != null && order.OrderDate.Value.Year > = year
