The correct option is A True
Non-biodegradable substances are the substances that can't be decomposed or degraded into simpler molecules by the action of microbes. Therefore these substances remain in nature for a long period of time. Such substances include plastic, polythene, metals, paints, polystyrene etc. These substances are also harmful for nature. They can be decomposed only by chemical agents.
Hence, the statement given in question is incorrect as non biodegradable articles cannot be decomposed or degraded.
So, the correct answer is 'True'.
