    Your answers are missing a factor of I1.

    How did you get I(SC) = (B+E)I1/(C+B+E) ?

    To get the answer just consider the mesh equation equations set up for the loop on the left with the voltage source, A and C in clockwise. Then, remembering that D is shorted, set up another mesh equation with the voltage source, A, B, E clockwise. Equate the two equations to eliminate the voltage source and you're done.
