b. db.AddToCustomers(customer);
c. db.Customers.Add(customer);
d. db.AddCustomer(customer);

Answer 1

Answer:

"mmaBooks.Customers.Add(customer);" is a correct answer for the above question.

Explanation:

Missing information : The correct answer is missing in the question which is defined in the answer part.

• If a user wants to add any objects to any collection in the C# programming, then he needs to follow the "Entity_data_model_named. collection_name. ADD(object_name)" syntax. The above question also wants this type of statement.
• The option c states the same statements, but there is needs one statement to define the name of db or database models. But the option c does not hold the name of the database models. Hence it is not the correct answer.
• And the other options do not follow the syntax to add, hence others is also not a valid option.
