What is the correct sequence of occurrence of the following cities in South-East Asia as one proceeds from south to north?

Correct Option

The correct sequence of cities from south to north is determined by their geographical latitudes.

• Jakarta (Indonesia) is located at approximately 6° South latitude.
• Singapore is located at approximately 1.3° North latitude.
• Bangkok (Thailand) is located at approximately 13.7° North latitude.
• Hanoi (Vietnam) is located at approximately 21° North latitude.

Therefore, proceeding from south to north, the order is Jakarta, followed by Singapore, then Bangkok, and finally Hanoi. This corresponds to the sequence 3–4–1–2.

Incorrect Options

Options 1 (4–2–1–3), 2 (3–2–4–1), and 4 (4–3–2–1) do not represent the correct geographical arrangement of these cities from south to north based on their latitudes. The accurate sequence is Jakarta, Singapore, Bangkok, and Hanoi.
