The correct answer is E. None of these.
The Kutumsar cave is a natural cave located in the Indian state of Madhya Pradesh. It is a popular tourist destination and is known for its beautiful rock formations. The cave was discovered in the 19th century and has been open to the public since the early 20th century.
Prof. Shankar Tiwari, Prof. Shankaranand Tiwari, Prof. Sewa Shankar Tiwari, and Prof. Ramshankar Tiwari are all Indian academics. However, there is no evidence that any of them were involved in the discovery or excavation of the Kutumsar cave.
It is possible that the question is based on a misunderstanding of the term “invented.” In this context, “invented” does not mean “created.” It means “discovered.” The Kutumsar cave was not created by any human being. It was discovered by humans.
