The correct answer is: c) 20 GW.
Gujarat is the largest producer of solar power in India, with an installed capacity of 20 GW as of 2022. The state has been a pioneer in the development of solar power, and its success has been driven by a number of factors, including a favorable policy environment, abundant solar resources, and a strong private sector.
Gujarat’s solar power sector has created thousands of jobs and has helped to reduce the state’s dependence on fossil fuels. The state’s solar power plants have also helped to improve air quality and reduce greenhouse gas emissions.
Gujarat’s solar power sector is expected to continue to grow in the coming years. The state has set a target of installing 30 GW of solar power by 2023. This target is achievable, given the state’s strong track record in the development of solar power.
The other options are incorrect because they do not represent the approximate installed capacity of solar power in Gujarat. Option a) is incorrect because it is too low. Option b) is incorrect because it is too high. Option d) is incorrect because it is not an option.
