Answer:
Option (1)
Step-by-step explanation:
A fjord is usually defined as a contrasting geological landform, which is typically a U-shaped valley, that is formed due to the movement of the glaciers. It is generally narrow and forms steep-sided cliffs on both the sides and is mostly connected to the seas. They have huge depth, sometimes reaches up to a depth of about 1300 m. The downward flowing glaciers pushes the terminal moraine and allows it to remain underwater at its entrance, resulting in shallow water at the fjord's neck, in comparison to the main body of the fjord that is located behind it.
Thus, the correct answer is option (1).
