Explanation: Khandagiri and Udhayagiri are two significant rock-cut cave sites located in the Poori district of Orissa (now Odisha), a state in eastern India. These caves are important for their historical and architectural significance, dating back to the 2nd century BCE. They were carved during the reign of King Kharavela of the Chedi dynasty, who ruled over the Kalinga region, which is now part of modern-day Odisha.
The Khandagiri and Udhayagiri caves are notable for their intricate carvings and inscriptions, which provide valuable insights into the religious, cultural, and social life of ancient India. The caves were primarily used as residences for Jain monks and are adorned with sculptures depicting various Jain Tirthankaras and other religious figures. The inscriptions found in these caves are written in the Brahmi script and provide information about the political and social conditions of the time.
The confusion might arise due to the geographical proximity of Orissa (Odisha) to other states like Bengal (West Bengal). However, it is important to note that the Khandagiri and Udhayagiri caves are distinctly located in the Poori district of Orissa. The state of Orissa was officially renamed Odisha in 2011, but the historical and cultural references to the region often still use the name Orissa.
Understanding the location and historical context of these caves is crucial for students of Indian history and archaeology. The caves are not only significant for their architectural beauty but also for the insights they provide into the religious and cultural practices of ancient India. Therefore, the correct answer is that Khandagiri and Udhayagiri hill chambers are located in the Poori district of Orissa (Odisha).
