Correct Answer: Option (C) — 3-4-1-2
Concept & Option Breakdown
Standard Reference VerifiedLatitudinal positions of the cities from South to North:
- Jakarta (Indonesia): ~6.2° S (in the Southern Hemisphere on the island of Java)
- Singapore: ~1.3° N (just north of the Equator on the southern tip of the Malay Peninsula)
- Bangkok (Thailand): ~13.8° N (central Thailand)
- Hanoi (Vietnam): ~21.0° N (northern Vietnam)
Thus, the south-to-north order is Jakarta (3) → Singapore (4) → Bangkok (1) → Hanoi (2).
Jakarta is located south of the Equator (Southern Hemisphere), making it definitively the southernmost city. This narrows the options to (b) and (c). Hanoi is in northern Vietnam near China, making it the northernmost, which confirms (c).
