You are designing a sequential circuit for a traffic light control system at a busy four$-$way intersection. The circuit

has the following requirements:

$$ It has eight distinct states representing different traffic light configurations.

$$ The system needs to minimize power consumption due to frequent state transitions.

$$ The logic complexity should be manageable to reduce the overall cost and size of the circuit.

Given this scenario, choose the most appropriate state assignment method from the options below. A$.$ One$-$Hot Assignment

B$.$ State Assignment with three guidelines $($also known as Karnaugh Map$-$based State Assignment$)$

C$.$ Straight $($Binary$)$ Encoding
