Explanation: During World War I, the industrial landscape of Gujarat underwent significant changes, particularly in the textile sector. Among the cities in Gujarat, Ahmedabad emerged as the center of industrial growth, especially in the textile industry. This growth was driven by several factors:
1. **Textile Industry Specialization**: Ahmedabad was already a major center for the textile industry before the war. The city had a well-established network of textile mills and factories, which were capable of producing a wide range of textiles, including cotton and silk fabrics.
2. **War-Induced Demand**: World War I led to a significant disruption in international trade, particularly in the textile sector. European countries, which were major producers and exporters of textiles, were unable to meet the global demand due to the war. This created a gap in the market that Ahmedabad's textile industry was well-positioned to fill.
3. **Government Policies**: The British government, which was in control of India at the time, encouraged the growth of industries in India to meet the war-related demands. This included providing incentives and support to the textile industry in Ahmedabad, which further boosted production.
4. **Infrastructure and Resources**: Ahmedabad had the necessary infrastructure and resources to support industrial growth. The city was well-connected by rail and road, facilitating the transportation of raw materials and finished goods. Additionally, the availability of skilled labor and a supportive business environment contributed to the growth of the textile industry.
5. **Economic Conditions**: The economic conditions during World War I favored the growth of industries in Ahmedabad. The war led to an increase in prices and demand for goods, which provided a favorable environment for industrial expansion.
In contrast, other cities in Gujarat, such as Bombay, Vadodara, and Gandhinagar, did not experience the same level of industrial growth during this period. Bombay, while an important industrial center, had a more diversified industrial base and did not see the same specialized growth in textiles as Ahmedabad. Vadodara, although it had some industrial activity, was not as focused on textiles and did not benefit as much from the war-induced demand. Gandhinagar, which was not yet established as a city during World War I, cannot be considered for this question.
Therefore, Ahmedabad saw the greatest growth in its mill and factory production during World War I, making it the correct answer to this question. This growth was a significant milestone in the industrial history of Gujarat and played a crucial role in shaping the city's economic landscape for years to come.
