Explanations:The question asks about a waterfall located on the Kaveri river in Dharmapuri district, Tamil Nadu. To understand the correct answer, it is essential to know the geographical and hydrological features of Tamil Nadu, particularly the location of the Kaveri river and the waterfalls associated with it.
The Kaveri river, also known as Cauvery, is one of the major rivers in southern India, flowing through the states of Karnataka and Tamil Nadu. It is a significant water resource for both states and supports agriculture, industry, and domestic use. The river originates in the Western Ghats and flows eastward, eventually draining into the Bay of Bengal.
Among the waterfalls associated with the Kaveri river, Hogenakkal waterfall is a notable landmark. It is located in Dharmapuri district, Tamil Nadu, and is known for its unique geological formation. The name "Hogenakkal" is derived from the Kannada language, where "Hogenakka" means "rocks that boil." This name reflects the appearance of the waterfall, where the water cascades over a series of rock formations, creating a boiling effect.
Hogenakkal waterfall is a popular tourist destination, attracting visitors with its natural beauty and the opportunity to experience the river's power. The waterfall is also significant for its ecological and environmental value, supporting a diverse range of flora and fauna.
Other waterfalls mentioned in the options, such as Kempty Fall and Kiliyur Waterfall, are located in different regions and are not associated with the Kaveri river or Dharmapuri district. Kempty Fall is in Sikkim, and Kiliyur Waterfall is in the Nilgiris district of Tamil Nadu.
Therefore, the correct answer is Hogenakkal waterfall, as it is the only waterfall on the Kaveri river located in Dharmapuri district, Tamil Nadu.
