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

The answer is D. The Suez Canal runs roughly north to south from Port Said on the Mediterranean to Suez on the Gulf of Suez, and it passes through a chain of lakes that you can place by latitude.

• Lake Manzala is the northernmost. It is a brackish coastal lagoon on the Mediterranean side, near Port Said, and the canal's northern reach runs along its southern edge.
• Lake Timsah comes next, beside Ismailia, the midpoint town of the canal.
• Great Bitter Lake lies south of Timsah and is the largest of the canal lakes. Ships use it as a passing and overtaking zone.
• Little Bitter Lake is the southernmost, just before the canal reaches Suez.

Option A reverses the sequence, and B and C scramble the order of the lakes. The core concept is the canal's geography: its route and the lakes along it, which matter for the Mains angle on chokepoints and global trade routes. Only the Suez Canal's strategic role, not the lake order, is usually tested in Mains.

Trap: Aspirants often assume Lake Timsah is north of the Bitter Lakes because it is the first lake the canal meets after Port Said. Check the latitude of each lake on a map before you answer.
