The "new safety standards for batteries" refers to a shift in the Technological environment because it involves improvements and changes in the methods and techniques of production (specifically battery safety tech).
The ”government ordered” standards and ”announced a reduction in import duties” fall under the Legal environment (legislation/government orders) and the Political environment (government policy). However, since the prompt links safety standards directly to battery overheating (tech) and orders/duties (legal/policy), the most accurate pairing provided in the options is Technological and Legal.
