4th option is correct i.e. River Godavari joins Bay of Bengal near Yanam.
The Godavari is the second longest river in India after the river Ganges having its source at Triambakeshwar, Maharashtra.
It starts in Maharashtra and flows east for 1,465 kilometres (910 mi) emptying into Bay of Bengal draining the Indian states Maharashtra (48.6%), Telangana (18.8%), Andhra Pradesh (4.5%), Chhattisgarh (10.9%), Madhya Pradesh (10.0%), Odisha (5.7%), Karnataka (1.4%) and Puducherry (Yanam) through its extensive network of tributaries. Measuring up to 312,812 km2 (120,777 sq mi), it forms one of the largest river basins in the Indian subcontinent, with only the Ganges and Indus rivers having a drainage basin larger than it in India. In terms of length, catchment area and discharge, the Godavari river is the largest in peninsular India and had been dubbed as the 'Dakshina Ganga' – the South Ganges river.
