    In the circuit below, A and B represents two inputs and C represents the output. The circuit represents:

    A) OR                   

    B) NOR  

    C) AND                

    D) NAND

    Correct Answer: C

    Solution :

    This circuit represents the AND gate. When potentials at A and B both are zero then both diodes are forward biased, revers biased then X is zero. When potential at \[\operatorname{B}=0, A=1, {{D}_{2}}\]is forward biased,\[{{D}_{1}}\]"X" is Zero.
