Which of the following best describes "green chemistry"?

Green chemistry is best characterized as a method for reducing harmful substances in chemical processes. This field focuses on designing chemical products and processes that minimize the use and generation of hazardous substances. The principles of green chemistry aim to provide environmental and economic benefits, promoting safer alternatives and reducing pollution at its source.

By prioritizing the reduction of hazardous materials, green chemistry seeks to create sustainable practices in the chemical industry, leading to safer products and overall environmental protection. This approach emphasizes innovation in chemical synthesis and process development to achieve a more sustainable future.

While other options touch on relevant concepts, such as sustainable supply chains or regulatory standards, they do not capture the core of what green chemistry seeks to achieve. Green chemistry is distinctly focused on the methods and practices that can be implemented to specifically reduce harmful impacts from chemical processes, which makes option B the most accurate description.
