Seemingly incorrect example of ng-style based on latest versions of Angular 1.x in quiz

The following question has incorrect use of ng-style: "Suppose I want to set the width and height of an element to two dynamic properties: ‘myWidth’ and ‘myHeight’, respectively. What syntax would I use to accomplish that?

A: <div ng-style="width = {{myWidth}}; height = {{myHeight}};">...</div>

B: <div ng-style="{width: myWidth; height: myHeight}">...</div>

C:  <div ng-width="myWidth" ng-height="myHeight">...</div>

D: <div width="{{myWidth}}" height="myHeight">...</div>

The correct answer amongst the options I picked, B, is technically incorrect since multiple properties should be separated by a comma not a semicolon.

I also tried the example with the correction I suspected w/ Plunker, what the AngularDocs uses for examples, with no problems.

On the other-hand, option B as is doesn't work. Perhaps this can be corrected before a complete Angular newbie goes astray if I'm correct?

P.S.: Also other questions in this quiz to review the sources the questions only go to the build your widget wrap up video (1.25 minutes) by Alex Vanston . That doesn't seem intentional.

Starting the majority of the vids 10+ days ago, this seemingly can be disorientating towards completion of the course.

Edit: The actual code snippets are being truncated; users can no longer use code blocks within the forums?
