The correct answer is option 3, Hoogli. The Hoogli River is a distributary of the Ganges River in West Bengal, India. It is known for having the highest tidal bore in India.

A tidal bore is a phenomenon in which a fast-moving tide rushes up a narrow river or bay, creating a wave-like effect. It occurs when the incoming tide meets a river or bay that is shallow and narrow enough for the tide to be constrained.

Option 1, Cauvery, is incorrect because the Cauvery River does not experience significant tidal bores. It is a large river in southern India known for its importance in agriculture and irrigation.

Option 2, Mahanadi, is incorrect because although the Mahanadi River is an important river in eastern India, it does not have a reputation for having a high tidal bore.

Option 4, Krishna, is incorrect because the Krishna River is a large river in southern India but does not have the highest tidal bore in the country.

Overall, the Hoogli River is recognized for its powerful tidal bore, making it the river with the highest tidal bore in India.
