Below we give four entries for the truth table of two point input OR gate. Which two are wrong? array cccc & A & B & Y i & 1 & 0 & 1 ii & 1 & 1 & 0 iii & 0 & 0 & 1 iv & 0 & 1 & 1 array

Options

  1. A(i) and (ii)
  2. B(ii) and (iii)
  3. C(iii) and (iv)
  4. D(iv) and (i)

Correct answer

B. (ii) and (iii)

Step-by-step solution

The Boolean expression for an OR gate is Y = A + B . Evaluating each given entry: For (i): A = 1, B = 0 Y = 1 + 0 = 1 . This is correct. For (ii): A = 1, B = 1 Y = 1 + 1 = 1 . The given value is 0 , so this is wrong. For (iii): A = 0, B = 0 Y = 0 + 0 = 0 . The given value is 1 , so this is wrong. For (iv): A = 0, B = 1 Y = 0 + 1 = 1 . This is correct. The wrong entries are (ii) and (iii). Answer: (ii) and (iii)
