The answer is B
Analysis: The characteristic of the distribution of ethnic groups in China is "large scattered, small clustered, and intermingled."

Ethnic minorities are mainly distributed in the southwestern, northwestern, and northeastern regions.

This pattern of ethnic distribution promotes interaction and cooperation among different ethnic groups, providing favorable conditions for the common prosperity of all ethnic groups. Therefore, option B is correct.
