Very good Nilarka Pahari and Khushie. Friends , the correct answer is B only. Just try to see . Tilt your head to your right and try to see the cuts at the end of the ribbons . You will find the error of your own. Did you find that? I know that only 5 to 37 percent of you can nfind the eight angles. Be very accurate and intelligent. I also did the same mistake while giving the test . Please look carefully!
