On which coast are backwaters or Kayals especially found?

Correct answer: Malabar Coast

Backwaters, locally called kayals, are a notable feature of the Malabar Coast, especially along Kerala. They are shallow coastal water bodies connected with the sea or influenced by marine water, and they may be separated partly from the open sea by sandbars, spits, or barrier formations. Their quiet waters and coastal setting distinguish them from ordinary inland rivers and lakes.

Option A is correct because the Malabar Coast of Kerala is especially known for its network of backwaters and kayals. The Coromandel Coast and Northern Circars have different coastal features, while the Konkan Coast is not the standard association asked for in this school geography fact. Remembering “kayals–Kerala–Malabar” provides a useful examination link. The question asks for the especially characteristic coast, not for every place where small coastal water bodies might occur.
