Geoff writes down the number 1. He then creates a list of numbers using the following process: He flips a fair coin. If the coin shows heads, he adds 1 to the preceding number in the list, and writes down the result as the next number in the list. If the coin shows tails, he subtracts 1 from the preceding number in the list, and writes down the result as the next number in the list. Using thisprocess, Geoff generates a list that has 12 numbers, including the first number of 1. For example,one such list might be 1, 2, 1, 2, 3, 4, 3, 2, 3, 4, 5, 6. How many distinct 12-number lists can Geoff create that have 8 as their last term? (A) 55 (B) 36 (C) 78 (D) 45 (E) Other
