Logic Gates

The circuit consists of two NOT gates, which are connected to two inputs A and B. The NOT gates invert the inputs A and B, producing the outputs and respectively. These outputs are then fed into an OR gate.
In an OR gate, the output is high (1) when at least one of the inputs is high (1). Therefore, in this circuit, the final output will be a logical OR of the inverted inputs.
The function of the circuit is equivalent to the OR gate, as the logic operation that connects the inputs through the NOT gates and the OR gate is characteristic of an OR gate.
Thus, the circuit represents an OR gate, and the correct answer is (B).
