Arrange the following zones in ascending order in terms of their latitudinal extent on the Earth surface : 1. Equatorial zone 2. Midlatitude zone 3. Subarctic zone 4. Tropical zone Select the answer using the code given below :

In this context, arranging zones in ascending order of their latitudinal extent means organizing them from the lowest latitude coordinates (near the Equator) to the highest latitude coordinates (towards the poles).

• Equatorial zone: Spans from 0° to 10° latitude.
• Tropical zone: Extends from 10° to 23.5° latitude (up to the Tropics of Cancer and Capricorn).
• Midlatitude zone: Located roughly between 23.5° and 66.5° latitude.
• Subarctic zone: Found in the higher latitudes, typically between 55° and 66.5° latitude (just below the Arctic Circle).

Sorting these zones by their distance from the Equator (0° to 90°) gives the ascending sequence: Equatorial → Tropical → Midlatitude → Subarctic. Thus, the correct code is 1 - 4 - 2 - 3.
