Explanation: The Teesta River, also known as the Tista River, is a significant river in northeastern India. It is a tributary of the Jamuna River, which is a major tributary of the Ganges. The river originates in the Himalayas, specifically in the Chumbi Valley in Tibet, and flows through the Indian states of Sikkim and West Bengal before joining the Jamuna River.
The Teesta River is an important river system in the region, playing a crucial role in the geography, economy, and culture of the areas it flows through. It is a major source of water for irrigation, drinking, and hydroelectric power generation. The river also supports a rich biodiversity and is home to various species of fish and other aquatic life.
The river's course through Sikkim and West Bengal is marked by several important towns and cities, including Jalpaiguri and Siliguri in West Bengal. The Teesta River is also known for its scenic beauty and is a popular destination for adventure sports like rafting and kayaking.
It is important to note that while the Teesta River does originate in the Himalayas, which includes parts of Tibet, it is not accurate to say that it originates solely in Tibet. The river's source is in the Chumbi Valley, which is located in the Tibet Autonomous Region of China, but the river flows through Indian territory as well.
In summary, the correct statements about the Teesta River are that it is a tributary of the Jamuna River and that it flows through the Indian states of Sikkim and West Bengal. The statement that it originates in Tibet alone is incorrect, as it originates in the Himalayas, which includes parts of both Tibet and India. Therefore, the correct answer is option C, which includes statements 1 and 3.
