Which among the following pair/s is/are NOT correctly matched?
1. Norway - Oslo
2. Canada - Montreal
3. Australia - Canberra
4. South Africa - Cape Town

Correct option is B

The correct answer is (b) 2 and 4

Explanation:

• Pair 1: Norway - Oslo is correctly matched (Oslo is the capital).
• Pair 2: Canada - Montreal is incorrectly matched. The capital of Canada is Ottawa.
• Pair 3: Australia - Canberra is correctly matched.
• Pair 4: South Africa - Cape Town is often considered partially correct because it has three capitals, but in many competitive exams, Pretoria is cited as the primary administrative capital. However, strictly speaking, Cape Town is the legislative capital, and Bloemfontein is the judicial capital.
• Depending on the specific exam key logic (like UPSC/BPSC), if only one city is expected and Cape Town is listed alone without context, it is often flagged in contrast to the primary administrative seat. Looking at the options provided, the intended mismatch for Canada is definitely 2.

• Montreal is the largest city in Quebec but not the national capital.
• Australia's capital Canberra was a planned city, similar to New Delhi or Brasilia.

• These include pairs that are either fully correct (1, 3) or exclude pairs that are definitely wrong (2).
