A $2$-bit flash Analog to Digital Converter $(ADC)$ is given below. The input is $0 \leq V_{IN} \leq 3$ Volts. The expression for the $LSB$ of the output $B_{o}$ as a Boolean function of $X_{2}, X_{1}$, and $X_{0}$ is
- $X_{0}\overline{\left[X_{2} \oplus X_{1}\right]} \\$
- $\overline{X_{0}}\overline{\left[X_{2} \oplus X_{1}\right]} \\$
- $X_{0}\left[X_{2} \oplus X_{1}\right] \\$
- $\overline{X_{0}}\left[X_{2} \oplus X_{1}\right]$
