Question

Which logic gate returns TRUE only if both inputs are TRUE?

• A. OR Gate
• B. NAND Gate
• C. XOR Gate
• D. AND Gate

Hint:

AND Gate follows the rule: TRUE AND TRUE = TRUE; all other cases are FALSE.

Answer 1

The Correct Option is D

Step 1: Understand logic gates.
Logic gates perform basic logical functions on one or more binary inputs.
Step 2: Analyze the AND gate.
An AND gate gives output TRUE only when all its inputs are TRUE.
Step 3: Compare with other gates.
OR Gate returns TRUE if any one input is TRUE.
NAND Gate is the opposite of AND Gate.
XOR Gate returns TRUE only when inputs are different.
Step 4: Conclusion.
Hence, the AND Gate returns TRUE only if both inputs are TRUE.
