This question comes from Brain Metrix's free IQ test(http://www.brainmetrix.com/free-iq-test/). This is the question:
I know that the answer is either option A or option C but I do not know whether it is A or C. I did find out a pattern of how the stick (the /) moves but I do not know how the dots move. I am also puzzled where by in the first and second pictures, there are 2 dots but in the third picture, there is only one. I do not know whether there is a mistake in the question or is there a pattern that explains why one dot disappeared and how the dots move. Any help in this puzzle is appreciated.
