beneficial
prolonged
ruinous
pornographic
Answer is Right!
Answer is Wrong!
The correct answer is C. ruinous.
A pernicious effect is one that is harmful or destructive. In the context of the question, the drug will have a harmful effect on the person’s health.
The other options are incorrect because they do not accurately describe the effect of the drug. Beneficial means helpful or advantageous, prolonged means lasting for a long time, and pornographic means relating to or depicting pornography.
Pornography is not relevant to the question, as the question is about the effect of a drug on health. Beneficial and prolonged are not accurate descriptions of the effect of the drug, as the drug is harmful and will not last for a long time.
