Option d is correct.

• Option a and b are incorrect: Kumaon and Nilgiri hills show annular drainage pattern. In such a pattern, the radial streams develop subsequent tributaries which try to follow a circular drainage around the summit.
• Option c is incorrect: Sahyadari hills show dendritic drainage pattern. River Krishna originates from these hills.
• Option d is correct: When the rivers originate from a hill and flow in all directions, the drainage pattern is known as ‘radial’. Rivers like Narmada, Son and Mahanadi originating from Amarkantak range flow in different directions and are good examples of radial pattern. This pattern is also found in the Girnar Hills of Gujarat and Mikir Hills of Assam.

Radial drainage pattern is a type of drainage pattern in which the rivers radiate outwards from a central high point, such as a volcano or dome-shaped mountain. This pattern is characterized by the presence of multiple streams that flow in different directions, resembling the spokes of a wheel.

The correct answer for the hill/range that depicts the radial form of drainage pattern is option 'D', Amarkantak range. Let's delve into the details to understand why this is the correct answer.

Explanation:

1. Radial Drainage Pattern:
A radial drainage pattern is formed when streams flow in different directions from a central point. This pattern is commonly observed in volcanic regions or areas with a centrally elevated landmass. The rivers in this pattern flow outward from the high point, forming a pattern similar to the spokes of a wheel.

2. Amarkantak Range:
Amarkantak range is located in the Maikal Hills of central India. It is a prominent hill range known for its religious significance, as it is the origin of the Narmada River, one of the major rivers of India. The Narmada River emerges from the Amarkantak plateau, which is essentially the central high point of the range.

3. Radial Drainage in Amarkantak Range:
The Amarkantak Range exhibits a radial drainage pattern because the rivers originating from the range flow in multiple directions, radiating outwards from the central high point. The Narmada River, along with its tributaries like the Johilla, Tawa, and Hiran rivers, flows in different directions from the Amarkantak plateau. This pattern is a clear example of a radial drainage system.

Conclusion:
Among the given options, the Amarkantak range is the correct answer as it exhibits a radial drainage pattern. The rivers originating from this range flow in different directions, resembling the spokes of a wheel. This pattern is a result of the central high point, the Amarkantak plateau, from which the rivers radiate outward.
