Is my truth table for this Logic Circuit correct?

Question

How would I make a truth table for this Logic Circuit

---

My attempt:

I think the logic expression would be along the lines of:

Z= −(−(A∧B)∨−(A∧B)∧−(B∧C))∧(−(A∧B)∧−(B∨C))

Answer 1

yes, the table is correct. The logic expression can be simplified to Z=0
