You are developing a C# application. The application includes a class named Rate. The following code
segment implements the Rate class:

You define a collection of rates named rateCollection by using the following code segment:
Collection<Rate> rateCollection = new Collection<Rate>() ;

When you execute the code, you get an exception.
You need to ensure that B_Products contain all of the products that start with the letter “B”.
What should you do?

You are modifying an existing application.
The application includes a Loan class and a Customer class. The following code segment defines the classes.

You populate a collection named customer-Collection with Customer and Loan objects by using the following
