The correct answer is: a) Fazilka.
Fazilka is a district in the Indian state of Punjab. It is located in the northwestern part of the state, on the border with Pakistan. The district has a population of over 1.5 million people.
Fazilka has a high potential for solar power generation due to its high solar insolation. The average annual solar radiation in Fazilka is 5.5 kWh/m2/day. This is significantly higher than the national average of 4.5 kWh/m2/day.
The district also has a number of advantages that make it ideal for solar power generation. These include:
- A large area of land that is suitable for solar panel installation.
- A good infrastructure for power transmission and distribution.
- A favorable government policy that supports the development of renewable energy.
As a result of these factors, Fazilka is one of the most promising locations for solar power generation in India.
The other options are incorrect because they do not have the same level of solar insolation as Fazilka. Gurdaspur, Firozpur, and Hoshiarpur all have average annual solar radiation of less than 5 kWh/m2/day. This means that they are not as suitable for solar power generation as Fazilka.
