✅ Given Gates:

• I. NAND
• II. NOR

✅ NAND Gate:

The NAND gate is functionally complete. It can be used to construct any logic gate (AND, OR, NOT, etc.) by combining multiple NAND gates.

✅ NOR Gate:

The NOR gate is also functionally complete. It can be used to construct any logic gate (AND, OR, NOT, etc.) by combining NOR gates.

✅ Final Answer:

Both NAND and NOR gates are functionally complete.
