Ah, I see what they're getting at. The question is asking us to identify the change that would make the diagram meet the requirement. I think option A is the correct answer, as a solid arrow with a closed head would clearly show the SoftwareSession being created by the User's activity.
Haha, this question is like a game of 'Spot the Difference' for UML diagrams. I'm going with option D - no change required. The diagram must already be depicting the SoftwareSession as being created by the User's activity, and the question is just trying to trick us.
This is a tricky one. I'm not sure if I agree with option C. Wouldn't it be easier to just remove the first activation on the SoftwareSession lifeline, as suggested in option B? That way, the diagram clearly shows the SoftwareSession being created by the User's activity.
Yeah, I think option B is the way to go. It would definitely make the diagram more accurate in depicting the creation of SoftwareSession by the User's activity.
I think option B makes the most sense. Removing the first activation on the SoftwareSession lifeline would clearly show the creation by the User's activity.
Hmm, it seems like the question is asking for a change to the diagram to show that a SoftwareSession is created by some activity of a User. I think option C is the correct answer, as it requires the arrow to cut at the tail of the SoftwareSession lifeline, indicating that the SoftwareSession is created by the User's action.
