Answer 1

The correct option is C QPR

Sentence S1S1 introduces that industries and transport cause pollution. The sentences Q and P are logically connected with S1S1 as they refer to the pollution caused by industries and automobiles. Sentence P uses the words 'further worsening' which means that Q comes before P. Sentence R and S5S5 refer to the harmful effects of pollution. Therefore, the logical order of the sentences is QPR and option c) is the correct answer.
