Answer 1

The Correct Option is C

- Bias (A) refers to prejudice or a preference for a particular sample or perspective (I).
- Prevalence (B) refers to the number of cases of a disease present in a population at a specific time (II).
- Placebo (C) is an inactive substance used in experiments to test the effectiveness of a drug (IV).
