The correct answer is: D. None of these
Ashoka the Great was a third-century BCE Indian emperor of the Mauryan Empire. He is best known for his role in the spread of Buddhism, and for his construction of many stupas and other Buddhist monuments. However, there is no evidence that he ever constructed a stupa in Yamunanagar.
The Shahpur Stupa is a Buddhist stupa located in Shahpur, Haryana, India. It is one of the largest stupas in India, and is believed to have been built in the 3rd century BCE. The Chaneti Stupa is a Buddhist stupa located in Chaneti, Haryana, India. It is a smaller stupa than the Shahpur Stupa, and is believed to have been built in the 2nd century BCE. The Dharmarajika Stupa is a Buddhist stupa located in Taxila, Pakistan. It is one of the oldest stupas in India, and is believed to have been built in the 3rd century BCE.
It is possible that Ashoka visited Yamunanagar, but there is no evidence that he ever constructed a stupa there.
