Answer :
A state transition diagram shows how an object changes from one state to another, depending on events that affect the object. The correct answer is Option B.
State transition diagrams are utilized to model the behavior of objects in systems. Objects can experience multiple states, and state transition diagrams depict how an object transitions from one state to another, depending on the events that occur as a result of the system's execution. State transition diagrams, also known as state machines, state-chart diagrams, and state diagrams, are utilized in object-oriented software engineering and software engineering to describe object behavior and interactions with other objects.
How are State transition diagrams useful?
A state transition diagram is useful for defining the states and transitions of a finite-state machine. When a system can be in one of a few discrete states, a state transition diagram is employed to represent the state transitions. State transition diagrams are helpful in system analysis, as they help users comprehend how the system works, and they may also be utilized as input to software testing tools. Additionally, state transition diagrams may be utilized to determine the number of states in a system or the minimum number of inputs required to transition from one state to another.
