This can only be solved by visualisation. However, we can easily eliminate E and B. If you know that visualisation question are hard and take time, skip them! and move on to the other simpler, workable questions. You can always come back and do it after when you have time. 
Also, ask your exams officer if you can take scissors into the exam. (rules don’t say you can’t bring scissors). Take permission though!.
