Step 1: Recall the Rohingya community.
The Rohingya are a Muslim minority living mainly in western Myanmar.
Step 2: Find their home region.
They are concentrated in Rakhine State, on Myanmar's western coast next to Bangladesh.
Step 3: Connect to the crisis.
Large-scale violence in Rakhine forced hundreds of thousands of Rohingya to flee into Bangladesh.
Step 4: Rule out the others.
Shan, Chin and Kachin are other states of Myanmar but are not the centre of the Rohingya crisis.
Answer: Rakhine (Option 3).
