P. The government has to invest in researching and developing alternate materials that are as versatile and useful as plastic.
Q. Meanwhile, heavy fines should be imposed on those producing, purchasing and using single-use plastic.
R. Plastic has engulfed the world and become an existential threat to most life forms.
S. Single-use plastic, in particular, is still rampantly used in India despite attempts to ban it.
Right Answer is: B
Sentence 1: The first sentence must introduce the subject matter of the paragraph to the reader. Sentence R does the same by introducing the topic of threat of plastic waste.
Sentence 2: In continuation of the previous sentence, Sentence S mentions a particular type of plastic which became a major problem as its use prevails even after a ban being imposed on it.
Sentence 3: Sentence P mentions a long-term solution to this problem which is a little time consuming but effective in a long go.
Sentence 4: Sentence Q mentions an instantaneous step need to be taken to combat the situation and concludes the paragraph.
Therefore, the correct sequence should be RSPQ.
