This is a reinforcement learning setting. The agent is in the state (H=9,x=1,y=2) where H is its health, and x and y is the location in a grid world environment. The agent meets a monster at (x=1,y=2), and there are several candidates for the next state:
1 (8, 1,2)
2  (11, 2, 5)
3  (5,1,3)
Use common sense logics to find the most possible option. Just give the option number, no explanation
