Can I play the idiot card for this question because I have fooled myself with answer sheets before? I marked the examination paper so that there was no doubt which answer I chose, I chose answer E but then circled D, which makes no sense. I correctly ruled out selection 2. I wasn't spamming the answer sheet here but actually made a "dumb" error. I was told to keep the paper at the end of the exam, but I have the evidence. It annoys me because I knew the answer. All the other ones I got wrong was fair play.
