MOSFET logic gates: Putting the pieces together
No, your current guess of "0001" is still wrong.

Here are some hints to get you going:


There are two separate logic functions here, one associated with each of the load resistors.
One of those functions has inputs D and E. Call its output Y.
The other function has inputs A, B, C and Y, and its output is Z.
Start by working out the full truth table for Y (four entries).
Then work out the full truth table for Z (16 entries).
Finally, in your tables, find the four specific results asked for in the problem statement.
