In the Suez canal region, the correct order of lakes lying from North to South direction is

1. A

   Lake Timsah-Little Bitter Lake-Great Bitter Lake-Luke Manzola

   This order starts at Timsah and ends at Manzala, which is south-to-north confused. Manzala is the northernmost lake on the Mediterranean side.

2. B

   Great Bitter Lake - Little Bitter Lake-Lake Timsah-Lake Manzala

   Great Bitter then Little Bitter then Timsah then Manzala runs largely south-to-north, the reverse of the asked direction.

3. C

   Lake Manzala - Great Bitter Lake - Little Bitter Lake-Lake Timsah

   Manzala then Great Bitter skipping Timsah is geographically wrong; Timsah lies between Manzala and the Bitter Lakes.

4. D

   Lake Manzala-Lake Timsah- Great Bitter Lake-Little Bitter Lake

   North to south along the Suez Canal: Lake Manzala (Mediterranean/Port Said side), Lake Timsah (Ismailia), Great Bitter Lake, Little Bitter Lake (towards Suez/Red Sea). That order is the official key.

Summary. Official key is (d). Suez lakes north→south: Manzala – Timsah – Great Bitter – Little Bitter.
