The symbolic representation of four logic gates are given in Fig.The logic symbol for OR, NOT and NAND gates are respectively

Options

A. (iv), (i), (iii)
B. (iv), (ii), (i)
C. (i), (ii), (iv)
D. (ii), (iv), (i)

Answer

B

Explanation

The given circuit represents an OR gate when either A or B or both inputs are high, the output C is high. OR gate, NOT gate and NAND gates are (iv), (ii) and (i) respectively
