    Step-by-step explanation:

    To solve this, I broke it down into two parts.

    A. Number of routes going to Town C

    4 x 3 + 2 = 14

    B. Number of routes going back to Town A

    3 x 4 + 2 = 14

    From here, it is easy to see what to do. Since there are 14 routes going to Town C and 14 routes going back, the answer is 14 x 14 = 196.
