Question

In which of the logic gate the following statement is true? "The output is high when either of the inputs is high but not if both inputs are high"

• A. NAND
• B. NOR
• C. X-OR
• D. OR

Hint:

This is the exclusive OR behaviour.

Answer 1

The Correct Option is C

Step 1: Test options
OR: output 1 when both are 1, which contradicts the statement. NAND: 1 for $(0,0)$, contradicts. NOR: 1 for $(0,0)$, contradicts.

Step 2: Result
Only XOR matches. Option (C).

Final Answer:
XOR. \[ \boxed{\text{(C)}\ \text{X-OR}} \]
