The correct answer is D.
Modern technology can help improve efficiency in mining by automating tasks, using sensors to monitor conditions, and using data to optimize operations. This can lead to reduced costs and increased production.
Modern technology can also help reduce environmental impact by using less energy and water, and by capturing and reusing waste products. This can lead to a cleaner environment and a more sustainable mining industry.
Modern technology can also help enhance safety by providing real-time data on conditions, warning miners of potential hazards, and providing remote monitoring and control. This can lead to fewer accidents and injuries.
Overall, the use of modern technology in mining can have a positive impact on efficiency, environmental impact, and safety.
