    Remember, these are vectors - direction matters. Look at the direction of your arrow of AB and \mathbf{a}. Now look at how you're travelling from B to C and then from C to D. When you're going from C to D, your direction of travel is opposite that of \mathbf{a}, so you're moving -3\mathbf{a} units to go from C to D.

    b) You've just got the wrong direction of the vector a
    d) You've also used the wrong sign for DC
