In the circuits shown the threshold voltage of each $\text{nMOS}$ transistor is $0.6\:V.$ Ignoring the effect of channel length modulation and body bias. the values of $\text{Vout}1$ and $\text{Vout} 2,$ respectively, in volts, are
- $1.8$ and $1.2$
- $2.4$ and $2.4$
- $1.8$ and $2.4$
- $2.4$ and $1.2$
