Explanation: The petrochemical industry is a critical sector in the Indian economy, and Gujarat has emerged as a leading state in this field. The rapid development of the petrochemical industry in Gujarat can be attributed to several factors:
1. **Strategic Location**: Gujarat is located on the western coast of India, which provides easy access to the Arabian Sea. This geographical advantage facilitates the import of raw materials and the export of finished products, making it an ideal location for petrochemical industries.
2. **Industrial Infrastructure**: The state has developed several industrial zones, such as the Gujarat Industrial Development Corporation (GIDC) and Special Economic Zones (SEZs), which provide the necessary infrastructure and incentives for industries to set up operations. These zones offer facilities like power, water, and transportation, which are essential for the petrochemical industry.
3. **Government Policies**: The Gujarat government has implemented supportive policies to attract investments in the petrochemical sector. These policies include tax incentives, land allocation, and streamlined regulatory processes, which make it easier for companies to establish and operate in the state.
4. **Availability of Raw Materials**: Gujarat has access to raw materials required for petrochemical production, such as crude oil and natural gas. The state's proximity to major ports like Mundra and Pipavav also helps in importing raw materials efficiently.
5. **Economic Growth**: The rapid growth of the petrochemical industry in Gujarat has contributed significantly to the state's economic growth. It has created employment opportunities and supported the development of ancillary industries, leading to a multiplier effect on the economy.
In contrast, other options like Mumbai, Delhi, and Goa do not have the same level of focus or infrastructure for the petrochemical industry. Mumbai, while a major industrial city, is more diversified and does not have the same level of petrochemical development as Gujarat. Delhi, being the capital, is more focused on administrative and service sectors. Goa, with its economy primarily based on tourism and agriculture, does not have the necessary industrial infrastructure to support rapid petrochemical growth.
Therefore, Gujarat stands out as the correct answer due to its strategic location, industrial infrastructure, supportive government policies, and the availability of raw materials, all of which contribute to the rapid development of the petrochemical industry in the state.
