The correct answer is: Mining.
Mining was traditionally a major industry in Goa. The state is home to rich deposits of iron ore, which was mined extensively from the 16th century until the early 21st century. The mining industry was a major source of employment and revenue for the state, but it also had a significant environmental impact. In 2012, the Supreme Court of India banned all mining in Goa due to concerns about the environmental damage.
Tourism is now the largest industry in Goa. The state is a popular tourist destination due to its beautiful beaches, colonial architecture, and laid-back lifestyle. Tourism generates billions of rupees in revenue each year and employs thousands of people.
Pharmaceuticals and information technology are also important industries in Goa. The state is home to several pharmaceutical companies and IT firms. These industries provide employment to thousands of people and contribute significantly to the state’s economy.
In conclusion, mining was traditionally a major industry in Goa, but it has been banned since 2012. Tourism is now the largest industry in the state, followed by pharmaceuticals and information technology.
