{'tributary': [0, 0, 0, 3], 'river': [4, 0, 1, 2], 'godavari': [0, 0, 0, 1], 'krishna': [0, 0, 0, 3], 'narmada': [20, 1, 18, 13], 'cauvery': [4, 1, 2, 7], 'bhavani': [0, 0, 1, 1], 'wainganga': [1, 0, 0, 1], 'amaravati': [2, 0, 0, 5], 'bhima': [2, 0, 2, 3]}

The given question asks us to identify the pair of a river and its tributary that is not correctly matched.

Option 1 states that Godavari is tributary to Wainganga. This is incorrect. In reality, Wainganga is a tributary of Godavari. A tributary is a smaller river or stream that flows into a larger river, and in this case, Wainganga flows into Godavari.

Option 2 states that Cauvery is tributary to Bhavani. This is correct. Bhavani is one of the main tributaries of the Cauvery river in the southern part of India.

Option 3 states that Narmada is tributary to Amaravati. This is incorrect. Narmada is one of the major rivers in central India and Amaravati does not flow into it.

Option 4 states that Krishna is tributary to Bhima. This is correct. Bhima is one of the main tributaries of the Krishna river in western India.

In conclusion, option 3 is the correct answer since Narmada and Amaravati are not a pair of a river and its tributary.
