Correct answer: C
Explanation:
(A' + B')'
= (A')' (B')'
= AB
To implement this using only NOR gates:
1. Use a NOR gate as an inverter for A: connect both inputs to A → gives A'.
2. Use another NOR gate as an inverter for B: connect both inputs to B → gives B'.
3. Use a third NOR gate with inputs A' and B' → output is (A' + B')' = AB.
Total: 3 NOR gates.
