Also note that there is a difference in naming between ASP.NET MVC and ASP.NET Core. In .NET Core, 'RequestType' does not exist. It is 'Method'. Only in ASP.NET MVC 'RequestType' exists. Confusing.

FINAL ANSWER: B is correct Any other solution is bad practice. You shouldn't check the RequestType property in the controller like that and D is not even here.

I disagree. The question is not about what is the good practice but rather which are the possible ways to achieve the goal. Last answer fulfills that requirement so is correct in my opinion. I saw lot of questions from MS that promoted bad practices so that one seems not to be exception. By the way - I have some sort of experience with MS exams and usually when the question is like "Select all that apply" it is really likely that there is more than single correct answer. It is not general rule but I have a feeling that assuming that there will be more than one may be good practice when taking MS exams. So I would say last two answers are correct and letters are assigned wrongly - first answer is skipped and to the second "A" has been assigned (should be "B" probably and so on).

C and D are the correct answers, if you can overlook all the 'c' instead of 's' typos in every answer choice that is..

B is also wrong since the retrieve returns variable s, which is undeclared.

C is also wrong since the retrieve returns variable s, which is undeclared. Perhaps I'm just being pedantic...

D is wrong since the variable c [c = RetrieveStudent(id)] is undeclared and the view being returned has no reference to argument s when saving a student.
