The correct answer is Mahanadi.
The Mahanadi river valley is known for its Paleolithic sites. The most famous of these sites is the Bhimbhetka rock shelter, which is located in the Kabirdham district of Chhattisgarh. The Bhimbhetka rock shelter contains a large number of rock paintings and engravings that date back to the Paleolithic period. These paintings and engravings depict a variety of scenes from the lives of early humans, including hunting, gathering, and religious ceremonies.
The Mahanadi river valley is also home to a number of other Paleolithic sites, including the Patalkot rock shelter, the Malhar rock shelter, and the Adamgarh rock shelter. These sites are all located in the Bastar district of Chhattisgarh.
The Paleolithic sites in the Mahanadi river valley provide valuable insights into the lives of early humans. These sites show that early humans were living in the region as early as 100,000 years ago. They also show that early humans were engaged in a variety of activities, including hunting, gathering, and religious ceremonies.
The Paleolithic sites in the Mahanadi river valley are a valuable part of the cultural heritage of Chhattisgarh. These sites are a reminder of the long and rich history of the region.
The Godavari river valley is located in the states of Maharashtra, Telangana, Andhra Pradesh, and Karnataka. The Narmada river valley is located in the states of Madhya Pradesh and Gujarat. The Indravati river valley is located in the states of Chhattisgarh and Odisha.
The Godavari, Narmada, and Indravati river valleys are all important rivers in India. However, none of these river valleys are known for their Paleolithic sites. The only river valley in India that is known for its Paleolithic sites is the Mahanadi river valley.
