What's wrong with D? In my opinion should be B and D. There is no guarantee of order between extension and controller related methods and variables

While a getter method is always required to access values from a controller, it’s not always necessary to include a setter method to pass values into a controller. Visualforce doesn’t define the order in which setter methods are called: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_controller_methods.htm

According to the dev guide, B doesn't seem correct. It says, "While a getter method is always required to access values from a controller, it’s not always necessary to include a setter method to pass values into a controller." So, setter is not required always.

You could say that alternative B is poorly written... Because it would be possible to interpret that 'a setter needs to pass a value's.... Just like 'passengers need to stay in their seats' or 'passengers are required to stay in their seats' But I could not find any evidence that C is correct

[quoting] "Getting and Setting Data with a Custom Extension or Controller There is no guaranteed order in which Apex methods and variables are processed by a controller extension or custom controller. Therefore, do not allow controller and extension classes to rely on another method being run, call that method directly. This applies specifically to setting variables and accessing data from the database." https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_controller_methods.htm

There are multiple ways to (B) pass the value from page to a controller so it's not *required*
