🚀 Step-by-Step Solution to Solve This Question 🚀
📌 Chapter: Semiconductor Devices
📌 Topic: Logic Gates – Boolean Expression Analysis

🔹 Step 1: Introduce the core concept
To determine the output of a logic circuit, we first identify each gate, follow the inputs through the circuit, and then derive the Boolean expression step-by-step.

🔹 Step 2: Explain how it applies here
In the circuit:

Input A goes through an inverter → becomes A bar

Input B goes through another inverter → becomes B bar

These two outputs (A bar and B bar) go into an AND gate

🔹 Step 3: Break down the reasoning step-by-step

First inverter G1: input A → output = A bar

Second inverter G2: input B → output = B bar

Final gate: AND gate receives A bar and B bar → output = A bar dot B bar

🔹 Step 4: Explain the final conceptual conclusion
This logic circuit is equivalent to an AND gate operating on the inverted inputs, and the Boolean expression is A bar dot B bar.

✅ Final Answer: (B) AND, A bar dot B bar 🚀
🔥 Pro Tip: When you see inverters before a gate, always write the inverted input first and then apply the gate’s logic. It helps avoid wrong interpretation in MCQs.
