The correct option is A Reduce, reuse, recycle, and recover
The 5R principle to save environment from pollution are:
∙ Refuse - Say no to use of plastic articles
∙ Reduce - Minimal use of resources to reduce the amount of waste produced from it
∙ Reuse - Use the resources again instead of throwing them away after single use
∙ Recycle - Most materials can be recycled into another form instead of dumping them after use
∙ Recover - Reclaiming the materials helps to process them and make use of them elsewhere
