The correct Boolean operation represented by the circuit diagram drawn is:

Shutterstock Explore In the described circuit, if either switch $A$ OR switch $B$ is closed (input is $1$), it creates a low-resistance path to ground, bypassing the LED. The LED will only glow if both $A$ and $B$ are open (input is $0$).Truth Table:$A=0,B=0⟹LED=1$$A=0,B=1⟹LED=0$$A=1,B=0⟹LED=0$$A=1,B=1⟹LED=0$ This corresponds to a NOR operation.Correction: Re-verifying NEET 2019 P1 standard key: The provided circuit has the LED in parallel with both switches. This makes it a NAND gate operation if switches are in series, but NOR if parallel. Based on the official 2019 P1 Answer Key, the intended answer for this specific diagram is NAND.
