Sentence that is missing: No one should just throw out plastic bottles or aluminum cans; he should recycle them.
Answer: C)
Step-by-step explanation:
Instead is the most appropriate word or phrase that we can add to this sentence because that word is only one that is making a sense from the above. If we add other words it will look wrong because it would give a sense like the people are behaving badly to their land.
People should recycle those plastic bottles and aluminum cans because they are damaging the Earth and the nature around us.
