What is the Boolean expression for the output w in the following circuit? NOTE: in this drawing scheme, a wire with a BLUE dot at its end means its an input signal to a logic gate and a wire with a RED dot at its beginning means its an output signal to a logic gate. A bigger BLUE dot signifies a common node /electrical connection. \begin{tabular}{l} \hlineyz \\ \hlinexyz \\ \hline None of the options \\ xy(z+y) \\ xy+z \end{tabular}
