$1$ Togle

Given the following two T$-$Flip$-$Flops that trigger on the positive$-$edge of the clock, answer questions $18$ and $19.$

$18.$ If the output $Q_0$ is connected to $CL{K}_1$ and the regular$/$master clock input is connected to $CL{K}_0,$ then the output $Q_1{Q}_0$ goes through the following sequence

a$.0001101100.$

$($b$.0001111000$dots

c$.0011100100$dots

d$.0011011000$dots

e$.0010110100$dots
