Step 1: Read the cartoon:
The cartoon shows the Sri Lankan leader Rajapakse walking along a thin stick. A lion marked Sinhalese sits at one end of it and a tiger marked LTTE sits at the other end.
The cartoon shows two groups pulling in opposite directions, while the leader tries to hold the balance.
Step 2: Identify the problem:
The two groups are the Sinhalas and the Tamils. They are divided by language and ethnic identity, and this led to a long civil war in Sri Lanka.
So the cartoon shows an ethnic conflict.
Step 3: Why the other options are wrong:
Economic imbalance (A): the cartoon has no sign of money or trade.
Political instability (B): the cartoon is about two communities, not about changes of government.
Regional conflict (C): the conflict is inside one country between two communities, not between regions or countries.
Final Answer:
The cartoon shows the ethnic conflict of Sri Lanka. The correct option is (D).
