Answer:
To determine which options are correct, let's analyze each option one by one:
a) 1, 2, and 3:
- NAND gates: A NAND gate can be used to implement any combinational circuit. This is because a NAND gate can be used to perform all the basic logic functions (AND, OR, and NOT) by combining multiple NAND gates together.
- NOR gates: Similarly, a NOR gate can also be used to implement any combinational circuit. Like NAND gates, NOR gates can perform all the basic logic functions (AND, OR, and NOT) when combined in different configurations.
- EX-OR gates: An EX-OR gate can also be used to implement any combinational circuit. This is because an EX-OR gate can be used to perform addition, subtraction, and other logical operations by combining multiple EX-OR gates together.
Thus, option a) is correct.
b) 1, 3, and 4:
- NAND gates: As mentioned earlier, NAND gates can be used to implement any combinational circuit.
- EX-OR gates: Similarly, EX-OR gates can also be used to implement any combinational circuit.
- Multiplexers: A multiplexer is a combinational circuit itself, so it cannot be used to implement any combinational circuit. However, it can be used as a building block in larger combinational circuits.
Thus, option b) is incorrect.
c) 2, 3, and 4:
- NOR gates: As mentioned earlier, NOR gates can be used to implement any combinational circuit.
- EX-OR gates: Similarly, EX-OR gates can also be used to implement any combinational circuit.
- Multiplexers: As mentioned earlier, multiplexers can be used as building blocks in combinational circuits, but they cannot implement any combinational circuit on their own.
Thus, option c) is incorrect.
d) 1, 2, and 4:
- NAND gates: As mentioned earlier, NAND gates can be used to implement any combinational circuit.
- NOR gates: As mentioned earlier, NOR gates can be used to implement any combinational circuit.
- Multiplexers: As mentioned earlier, multiplexers can be used as building blocks in combinational circuits, but they cannot implement any combinational circuit on their own.
Thus, option d) is correct.
Therefore, the correct answer is option d) 1, 2, and 4.

- Multiplexers: As mentioned earlier, multiplexers can be used as building blocks in combinational circuits, but they cannot implement any combinational circuit on their own.
Thus, option d) is correct.
Therefore, the correct answer is option d) 1, 2, and 4.
