Logic Gates question from MHT CET 2024 (11 May, Shift 2)

Answer: (d)

1. The triangle on A has a bubble, so it is a NOT gate: it gives $\bar{A}$.
2. NAND gate: $Y = \overline{\bar{A} \cdot B} = A + \bar{B}$.
3. Rows $AB = 00, 01, 10, 11$ give $Y = 1, 0, 1, 1$.
4. This is table R, so the answer is (d).
