i believe the correct answer is C. This pattern repeats every 9 letters. So we want to find out what the remainder is when we divide 369 by 9. That will tell us which letter the 369th term is. It turns out that 369 is perfectly divisible by 9, so it should be the ninth letter in the sequence, which is C.
