Final answer:
The statement is true. A state model can be used to derive test cases based on the dynamic behavior of an object-oriented system.
Step-by-step explanation:
The statement that the state model can be used to derive test cases based on the dynamic behavior of an object-oriented system is true. A state model is a representation of the various states that an object goes through during its lifetime, and it can be used to identify all possible test cases to ensure the system functions correctly in different states. For example, if you have an object representing a light bulb, the state model can include the states 'on', 'off', and 'dimmed', and you can derive test cases to cover the transitions between these states.
