A sequential logic circuit has one input (x), one output (z), and six states labeled A-F. The circuit is described by the state table shown below. Entries in the two right-hand columns represent the next-state/output-value combination for each present-state condition and input value.
For example, if the present state is B and an input x= 1 is applied, the next state will be D and the value of z will be 0.
If the circuit is initially in State C and the input sequence x = 100 is applied (meaning the first input is 1, the second input is 0, etc.), the output sequence is best described by:
A. 101
B. 010
C. 100
D. 111
