• B. Drip irrigation technology
• C. Pyrolysis of hazardous medical wastes
• D. Green Crackers

Answer 1

The correct option is D Green Crackers

Explanation:

These are terms associated with green crackers named Safe Water Releaser (SWAS), Safe Thermite Cracker (STAR) and Safe Minimal Aluminium (SAFAL) crackers. The Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI) has been working since January 2018 to develop new and improved formulations for reducing emissions from fireworks. It developed new formulations for reduced emission light and sound emitting crackers (SWAS, SAFAL, STAR) with a 30% reduction in particulate matter using Potassium Nitrate (KNO₃) as an oxidant.
