The circuit is equivalent to

A)  NOR gate           

B)  AND gate

C)  NAND gate       

D)   OR gate

Correct Answer: C

Solution :

Consider the gate circuit with inputs Different outputs are                 \[{{Y}_{1}}=\overline{AB}\]                 \[{{Y}_{2}}=\overline{\overline{AB}}=AB\]                 \[Y=\overline{{{Y}_{2}}}=\overline{AB}\] Which is the output of \[NAND\] gate.
