CONCEPT:
  • OR gate - The OR gate is defined as the gate in which if one of the inputs is true then the result will also true.
  • AND gate - The AND gate is defined as the gate in which if one of the inputs is false then the result will also false.
  • NOT gate - The NOT gate is defined as the output attains state 1 if and only if the input does not attain state 1.
  • NOR gate - NOR gate is defined as it is the combination of NOT and OR gate.
CALCULATION:
Let us the different cases.
Case I - When A = 0, B = 0
The LED will glow.
Therefore, Y = 1
Case II - When A = 1, B = 0
The LED will not glow.
Therefore, Y = 0
Case III - When A = 0, B = 1
The LED will not glow.
Therefore, Y = 0
Case IV - When A = 1, B = 1
The LED will glow.
Therefore, Y = 0
The truth table is written as;

Here we see the results it will show the nature of NOR.
Hence, option 3) is the correct answer.
