B and C. The question states that you need to replace "Hello" with "Goodbye" in the parameter that is passed to the SendMessage() method. It doesn’t state that you need to change the value of the message variable.

B is the only correct answer. Method String.Replace create a new string, it does not change the value of the existing string.

At least now C is also correct since the result of the Replace() method is assigned to the message variable
