Logic Gates question from JEE Main 2023 (24 Jan, Shift 2)

Q104JEE Main 2023 · 24 JAN · SHIFT 2Medium

Logic Gates

The logic gate equivalent to the given circuit diagram is:

Show answer and solution

Answer: (c)

Switches $A_1$ and $B_1$ are in series, and this branch is across the LED.
Only when both are closed is the LED shorted ( $Y = 0$ ).
Otherwise it glows: $Y = \overline{AB}$ .
So the answer is (c) NAND.
