UPSC CSE Prelims 2005
The correct sequence of towns from north to south is Peshawar–Islamabad–Gujranwala–Multan.
Option (a) Islamabad–Gujranwala–Peshawar–Multan is incorrect. Peshawar is geographically located north of both Islamabad and Gujranwala, disrupting the north-to-south order.
Option (b) Peshawar–Gujranwala–Multan–Islamabad is incorrect. Islamabad is situated north of Gujranwala and Multan, therefore it cannot be the southernmost city in this sequence.
Option (d) Islamabad–Multan–Peshawar–Gujranwala is incorrect. Multan is located south of Peshawar and Gujranwala. Peshawar is the northernmost city among the given options, rendering this sequence geographically inaccurate.
