The question deals with a geographical map that has four cities labeled as A, B, C, and D. The task is to match these labeled cities with their corresponding names from the given list. Each city corresponds to a distinct number ranging from 1-5. The correct answer is option 1: A-1, B-2, C-4, D-3.

In option 1, A matches with Darwin (1), B with Kuala Lumpur (2), C with Nairobi (4), and D with Lagos (3).

Option 2 swaps the position of Darwin and Kuala Lumpur, which was identified as an error. Option 3 assigns A to Darwin and B to Nairobi, which is incorrect, and also changes the cities for C and D. Option 4 suggests that A is Nairobi, which is incorrect, and although it correctly identifies Lagos, the other cities are wrong.

The correct sequence of matches is provided in Answer 1: Darwin, Kuala Lumpur, Nairobi, and Lagos are cities A, B, C and D respectively.
