  1. A state diagram of a logic gate which exhibits a delay in the output is shown in the figure, where X is the don’t care condition, and Q is the output representing the state.

    The logic gate represented by the state diagram is
    1. XOR
    2. OR
    3. AND
    4. NAND
Correct Option: D


If you will observe this true table corresponding to state diagram, then if any input is 0 output is 1 and if all the inputs are one output is zero it means it corresponds to NAND gate.
