4. Siliguri is at a lower elevation than Gangtok

• A. Only ii
• B. Only ii and iii
• C. Only ii and iv
• D. Only iii and iv

Answer 1

Using fist letter to denote the cities, we can arrange them in the order of elevations as ($,$ means order is not sure)

$\{\{S < P\}, K\}<G < D$

So, options (ii) and (iv) can be concluded whereas we are not sure about (i) and (iii).

Correct Option: C.
