Which of the following logic gates will have an output of '1' (one) for the given inputs?

Step-by-step solution

Let us evaluate the output for each logic gate given in the options: For gate (A): It is a NAND gate with inputs 1 and 1 . Output Y = 1 1 = 1 = 0 For gate (B): It is a NAND gate with inputs 1 and 0 . Output Y = 1 0 = 0 = 1 For gate (C): It is a NOR gate with inputs 0 and 1 . Output Y = 0 + 1 = 1 = 0 For gate (D): It is an XOR gate with inputs 0 and 0 . Output Y = 0 0 = 0 Therefore, only gate (B) has an output of 1 . Answer: B
