Can you guys help me on this song i would love it

answer; i believe the correct answer is (e) it is too dangerous just for the sake of promoting ratings;

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.  

i think it's but if you get it wrong its not my fault : )
