Answer 1

Hint: Backwaters or 'Lagoons' are small water bodies isolated by land from the open sea.
One of the most attractive and economically important aspects of this state is the backwaters.
Waterways provide rivers, channels and rivers, as well as lakes, reservoirs and docks. Which are linear features of the water.

Complete answer:
Kerala's backwaters are a network of brackish lagoons and lakes situated parallel to the coast of the state of Kerala in the Arab Sea of southern India (known as the Malabar Coast). The network comprises five wide canals connected by manmade and natural canals, which feed the 38 rivers and stretch almost half the length of the state of Kerala. Waves and bank streams created the rear waters that created low barrier islands around the mouths of the many streams from the western ghats.
Compared to other large countries and geographic regions, such as the United States, China and the European Union, freight transport by waterway is highly underused in India. The total cargo transported by inland waterways (in tonne kilometres) was 0.1 percent of total inland traffic in India, compared with 21 percent for the United States.

Kerala which is Option B is the correct answer.

Note: The world's most popular lagoon, Iceland's Blue Lagoon, is not at all a lagoon. It is a man-made feature in which water is pumped through a lava bed rich in silica and sulphur from a nearby geothermal power generation. These elements react to a bright, blue lake used as a spa through the warm water.
