In which country does the sausage Sai Ua originate?
Correct answer: Thailand

little b
my support worker Julie Anderson went to Thailand

Republic of China
How is "Sai Ua" a dish of North Korea? I thought 2nd most voted option was something else and also "Sai Ua" does not sound like the North Korean language
Every dish is named in their native language and "Sai Ua" is not Korean name for the dish.
If you learn languages (German, Chinese, Japanese, etc) which I did, the question would be simple.
Just know the dish name and jus to check if the word makes sense to the countries listed in the options (For example, Greece = Greek)
