The question presents two statements for consideration: 1) In Macedonia, ethnic Albanians are a minority and 2) In Kosovo, Serbians are a majority. Clarification is sought regarding the validity of these statements.

Option 1 asserts that only the first statement is correct. Ethnic Albanians indeed constitute a sizable minority in Macedonia, so this statement is accurate.

Option 2 claims that only the second statement is correct, indicating that Serbians form the majority in Kosovo. However, this is incorrect as the majority in Kosovo are ethnic Albanians, not Serbians.

Option 3 suggests that both statements are correct. As explained above, only the first statement is true, while the latter is false.

Option 4 contends that neither statement is correct. This is also false as the first statement is indeed correct.

Therefore, the answer provided, Option 2, is incorrect. Serbians are not a majority in Kosovo. Alert - correct answer should be: Only 1.
