Explanations:Jharkhand is a state in eastern India, known for its rich mineral resources and industrial towns. The state was formed on 15th November 2000, carved out of the southern part of Bihar. Jharkhand is home to several important towns that play a significant role in the state's economy and industrial landscape.
Among these towns, Dhanbad, Bokaro, and Jamshedpur are particularly noteworthy. Dhanbad is often referred to as the "coal capital of India" due to its extensive coal reserves and mining activities. It is a major industrial center and is also known for its educational institutions, including the Indian School of Mines.
Bokaro is another important industrial town in Jharkhand, known for its steel plants and coal mines. The Bokaro Steel Plant, established in 1964, is one of the largest steel plants in India and has been a significant contributor to the state's economy.
Jamshedpur, also known as "Steel City," is the first planned industrial city in India. It was founded by Jamshedji Tata, the founder of the Tata Group, and is home to the Tata Steel plant. The city is a major industrial hub and is known for its steel production and other manufacturing activities.
These towns are integral to Jharkhand's industrial and economic development. They are not located in other states such as Bihar or Assam, which are geographically and administratively distinct. Therefore, the correct answer is that Dhanbad, Bokaro, and Jamshedpur are important towns of Jharkhand.
