The output ($Y$) of the given logic gate is similar to the output of an/a :
Answer: (B) AND gate
The first gate is a NAND gate with both inputs joined to $A$, so it acts as a NOT gate: output $\bar{A}$.
The second gate is a NOR gate with both inputs joined to $B$, so it also acts as a NOT gate: output $\bar{B}$.
The final NOR gate gives
$$Y = \overline{\bar{A} + \bar{B}} = A \cdot B$$
(De Morgan's theorem), which is the AND function.
