Explanation:

Dhuandhar Falls:

The Dhuandhar Falls is located on the Narmada River in Bhedaghat and are 30 meters high. The Narmada River, making its way through the world-famous Marble Rocks, narrows down and then plunges into a waterfall known as Dhuandhar. The plunge, which creates a bouncing mass of mist, is so powerful that its roar can be heard from a far distance. The white marble rocks appear spectacular when the moonlight falls on them, rendering them a silvery appearance. Hence pair 1 is correctly matched.

Shivanasamudra Falls:

The Shivanasamudra Falls is on the Kaveri River after the river has found its way through the rocks and ravines of the Deccan Plateau and drops off to form waterfalls. The island town of Shivanasamudra divides the river into twin waterfalls. This creates the fourth-largest island in the course of the river.

This is a segmented waterfall. Segmented waterfalls occur where the water flow is broken into two or more channels before dropping over a cliff, resulting in multiple sides by side waterfalls. It has an average width of 305 metres and a height of 98 m. It is a perennial waterfall. Hence pair 2 is correctly matched.
