Biodegradable items can be degraded into simpler molecules by the action of microbes. These include grass, flowers, leather, wood, fruit peels, cake, lime juice etc. All these items can be decomposed by microorganisms.
Plastic is non-biodegradable as it can't be decomposed by the action of microorganisms and thus, it remains in nature for a long period of time.
So, the correct answer is option A, C and D.
