Sacred groves are known as Kavu in which state of India?

The correct answer is A, Kerala. In Kerala a sacred grove is called a Kavu, and a grove kept for the serpent deities, which almost every old family compound of the state once had, is called a Sarpa Kavu. These groves are small, dense and often hold the last remnant of the original wet evergreen vegetation of their locality, along with a tank or a spring.

Option B is wrong because the Karnataka name is Devarakadu, literally the forest of god, best known from the Kodagu district. Option C is wrong because in Odisha such groves are called Jahera or are named after the goddess Thakuramma. Option D is wrong because the groves of Manipur are the Umang Lai, the sacred woods of the forest deities worshipped in the Lai Haraoba festival. Learning the name with the state is the quickest way to clear this family of questions.
