Explanation:

AS per the second paragraph, the focus of reducing plastic pollution is focused on changing consumer behaviour instead of targeting the plastic producers who produce plastic on a large scale. Option 1 is incorrect as the second paragraph states that producing single-use plastic is the wrong use of technology. However, nothing has been mentioned about using technology to solve the ill-effects of plastic pollution. Negate it. Encouraging responsible production of plastic by firms is mentioned in the last paragraph which negates option 2. Option 3 correctly gives the meaning of phrase ‘what hammering a nail is to halting a falling sky-scraper’. Retain it. As per the fourth sentence of the second paragraph, not single use plastic, but the producers of single use plastic items are behind the plastic pollution problem. Thus option 4 is also incorrect and can be negated.
Hence, the correct answer is option 3.
