Explanations:The textile industry, particularly the cotton textile industry, is a significant part of Gujarat's economy and history. The city of Ahmedabad, located on the banks of the Sabarmati River, is a major hub for the cotton textile industry. This industry has a long and rich history in the region, dating back to the 19th century when the first textile mills were established. The cotton textile industry in Gujarat has been a major contributor to the state's economic growth and development.
The Sabarmati River plays a crucial role in the textile industry of Gujarat. The river provides water for the mills and factories, and its banks have been the site of numerous textile mills and weaving industries. The proximity to the river has historically made it easier to transport raw materials and finished products, contributing to the growth and success of the industry.
While Gujarat does have other industries such as iron and steel and fertilizer production, these are not as prominently located on the banks of the Sabarmati River as the cotton textile industry. The iron and steel industry, for example, is more concentrated in other parts of the state, and the fertilizer industry, although present, is not as historically significant or economically dominant in the region.
Therefore, the correct answer to the question is the cotton textile industry, which is located in Gujarat on the banks of the Sabarmati River. This industry has played a vital role in the economic and social development of the region and continues to be a significant part of Gujarat's industrial landscape.
