“Pernicious” means harmful in a gradual or subtle way. Sentence i correctly describes the long-term, harmful effects of smoking. Sentence ii seems incorrect because “pernicious” is usually used in a more serious or harmful context, not for everyday discomfort. Sentence iii misuses the word, as “pernicious” generally refers to something insidious, not an immediate illness. Option 1 is correct.
