Option (B)
Explanation:
A lagoon is defined as a shallow water body that is often separated by a larger water body such as oceans by a coral reef or sandbars. This lagoons are of 2 types, namely the coastal lagoon and the atoll lagoon.
(1) Coastal lagoon-This type of lagoons are protected by sandbars or barrier islands. They usually form along coastal areas with small range in the tidal. They are shallow type of basin that are present near the gradually eroding shore.
(2)Atoll lagoon- They are almost similar to the coastal lagoons, but they are mostly protected by the coral reefs. These are commonly found in the oceans of tropical regions.
Thus, the correct answer is option (B).
