| We know that in XOR gate same input is 0 and different input is 1. For eg, suppose A=1 and B=1 i.e same input. So the result will be 0. So the correct answer is "A". |

| Option A = 10 11 11 00 A XOR B = 1 XOR 0 => 1 C XOR D = 1 XOR 1 => 0 E XOR F = 1 XOR 1 => 0 G XOR H = 0 XOR 0 => 0 (A XOR B) XOR (C XOR D) = 1 XOR 0 => 1 .....(1) (E XOR F) XOR (G XOR H) = 0 XOR 0 => 0 .....(2) (1) XOR (2) = 1 XOR 0 => 1. Hence the Option A is correct. |

| XOR is odd function, so if : # of 1 is odd , y = 1. # of 1 is even , y = 0. So when look to the options, In option a : # of 1 = 5 (odd) so y =1 |

| What's an odd function? | |

| Looking the options where the number one is in odd that is the answer. | |
