Correct answer: C

A 4-to-1 multiplexer selects one of its four inputs based on the binary combination of its select lines. Here, the select lines are A and B, where A acts as the Most Significant Bit (MSB) and B acts as the Least Significant Bit (LSB).

The general output equation for a 4-to-1 multiplexer is given by:

From the provided circuit diagram, the inputs are mapped as follows:
