Congratulations! Your method for Q3c and the solutions are perfectly correct.

Similar ideas apply for 3d.

I choose x = 0 to kill off A and B, having observed that A and B are attached to x. I can find C from there.

Next, x = 1 kills off A and I can get B.

Finally, x = any number except 0, 1 and 3 to find A.

I will only be able to answer further questions after 12 am.
