Help with question

[Diabolical Artificer]

I really dislike multiple choice questions, to my mind they make the problem more difficult rather than easier as was intended originally. When I was taking my CSE's at school exams were given in the format of a question and a space to show your answer with emphasis of your reasoning and method. Reading Mikes Capacitance Q answers and my brain explodes, it's deliberately obtuse and opaque not to mention confusing. Well done mike for getting through it, I'm like yourself, I learn better by doing where I can see and feel a problem, I need to get my digits involved to ensure proper cogitation.
