The method that will ensure the thread will be in running state is notify(). Here's a step-by-step explanation:

1. yield(): This method causes the currently executing thread object to temporarily pause and allow other threads to execute. It does not guarantee the thread will be in running state.

2. wait(): This method tells the calling thread to give up the monitor and go to sleep until some other thread enters the same monitor and calls notify(). So, it also does not guarantee the thread will be in running state.

3. notify(): This method wakes up a single thread that is waiting on this object's monitor. If any threads are waiting on this object, one of them is chosen to be awakened. Thus, it ensures the thread will be in running state.

4. Thread.killThread(): There is no such method in Java Thread class.

So, the correct answer is notify().
