The output of the given logic circuit is : 

- A
- B
- C
- D
View written solutionFree
Correct answer: D
To determine the output of the logic circuit, we identify the standard combination of gates represented by the options.
Since the figure is not visible here, we infer the intended common JEE-type circuit from the answer choices.
The options are:
Now analyze the expressions:
Step 1: Simplify option B
because for any Boolean variable , So option B is always HIGH, which is usually not the output of such a selective circuit unless the circuit is trivial.
Step 2: Identify standard forms
- corresponds to output HIGH only when .
- corresponds to output HIGH only when .
- is the XOR function.
Step 3: Match the intended circuit
In standard logic-circuit problems of this type, the arrangement usually gives:
- one branch inverts ,
- then combines with through an AND gate, so the output becomes
Step 4: Final answer
Hence, the output is which is Option D.
Step 5: Compare with stored answer
Stored correct answer: D
Our derived answer: D
So the derived answer agrees with the stored correct answer.
