The correct option is A Eco mark
To increase consumer awareness, the Government of India launched the eco-labelling scheme known as ‘Ecomark′ in 1991 for easy identification of environment-friendly products. Any product which is made, used or disposed of in a way that significantly reduces the harm it would otherwise cause the environment could be considered as Environment-Friendly Product. The ′Ecomark′ label is awarded to consumer goods which meet the specified environmental criteria and the quality requirements of Indian Standards. Any product with the Ecomark will be the right environmental choice.
