JEE Main 6 April 2023, Shift 1, Physics Q32

Question 32 of 90 in this shift, Physics question 2 of 30, Section A.

Name the logic gate equivalent to the diagram attached

The figure, in words

Circuit: +5V supply with two parallel branches, each having a switch (A and B respectively; each switch has contact position 1 connected to the +5V side and open position 0); the two switch outputs join and go to resistor R to ground; LED output Y across R side (1 = Glow).
