The question requires knowledge about where these communities are usually involved when mentioned in the news.

Option 1 suggests that Kurds are linked to Bangladesh, which is incorrect. Kurds are a significant ethnic group in the Middle East, primarily in regions such as Turkey, Iraq, Iran, and Syria. Hence, association with Bangladesh is not correct.

Option 2 correctly posits that the Madhesi community is linked with Nepal. The Madhesis are an ethnic group native to the Terai region in Nepal. They are often highlighted in the news concerning socio-political conflict in Nepal.

Option 3 includes both the Madhesi-Nepal and Rohingya-Myanmar pairs which is correct. Rohingya are an ethnic Muslim minority group in Myanmar, often mentioned news due to the severe humanitarian crisis and violations of human rights.

Option 4 only includes Rohingya-Myanmar pair which is correct but misses out on the correctly associated Madhesi-Nepal pair.

Therefore, the correct answer is option 3, which correctly matches both pairs, Madhesi with Nepal and Rohingya with Myanmar.
