Option B: (ii) and (iii)
Ball point pen refills (plastic) and empty medicine bottles made of glass are non-biodegradable, as they cannot be broken down by biological processes.
Non-biodegradable substances are those not broken down by bacteria or other biological agents. Garden waste, fruit/vegetable peels, and cotton (natural fibre) are all biodegradable. Plastic (pen refills) and glass (medicine bottles) are human-made/inorganic materials that persist in the environment — exactly the type described in the textbook as non-biodegradable.
