Which of the following is not a valid state for a thread to be in?

Running
Sleeping
Waiting
Flying

The correct answer is: Flying

Flying is not a valid state for a thread to be in because threads are used to execute code within a program and do not have the ability to physically move or fly. The other options (Running, Sleeping, Waiting) are all valid states for a thread to be in as they represent different stages of the execution process. Running indicates that the thread is currently executing its code, Sleeping indicates that the thread is temporarily suspended, and Waiting indicates that the thread is waiting for a certain condition to be met before it can continue execution.
