Explanation:
To implement a 2-input XOR gate using 2-input NAND gates, we can use the following logic:
1. Connect the two inputs A and B to two separate NAND gates (N1 and N2).
2. Connect the output of N1 to one input of another NAND gate (N3).
3. Connect the output of N2 to the other input of N3.
4. Connect the output of N3 to the input of another NAND gate (N4).
5. Connect the output of N1 to one input of another NAND gate (N5).
6. Connect the output of N2 to the other input of N5.
7. Connect the output of N4 and N5 to two separate inputs of another NAND gate (N6).
8. The output of N6 is the output of the XOR gate.
Calculation:
We can see that we need a total of 6 NAND gates (N1 to N6) to implement a 2-input XOR gate using 2-input NAND gates. Therefore, the correct answer is option A (4 is not enough and options B and C are too many).
Conclusion:
Thus, the minimum number of 2-input NAND gates required to implement a 2-input XOR gate is 6.
