    The following figure represents a logic symbol, this is equivalent to :

    A)  NAND gate                       

    B)  NOT gate

    C)  OR gate                              

    D)  AND gate

    Correct Answer: D

    Solution :

                    This is a combination of logic gates, the first one represents NAND gate, it will make C = AB , the spend circuit represents a NOT gate Hence, it makes \[Y=\overline{AB}=AB\] So, equivalent circuit represents AND gate
