The correct answer is: Industrial clearances and approvals.
A single window system is a government initiative that aims to simplify the process of obtaining approvals and clearances for businesses. It does this by providing a single point of contact for businesses to interact with the government, and by streamlining the process of obtaining approvals. This can save businesses time and money, and can help to improve the ease of doing business in a country.
Industrial clearances and approvals are a major obstacle for businesses in many countries. The process of obtaining these approvals can be complex and time-consuming, and businesses often have to deal with multiple government agencies. This can be a major barrier to investment and growth.
A single window system can help to address these challenges by providing a single point of contact for businesses to interact with the government. This can make it easier for businesses to understand the requirements for obtaining approvals, and can help to speed up the process.
The single window system can also help to improve coordination between government agencies. This can help to reduce the time and effort that businesses need to spend dealing with multiple agencies.
Overall, a single window system can be a valuable tool for businesses. It can help to simplify the process of obtaining approvals and clearances, and can help to improve the ease of doing business in a country.
