Answer 1

The Correct Option is C

The correct matches are:

• A. True-positive: Person has disease and screening test result is positive (IV). This indicates the test correctly identifies those with the disease.
• B. True-negative: Person does not have disease and screening test result is negative (II). This indicates the test correctly identifies those without the disease.
• C. False-positive: Person does not have disease and screening test result is positive (I). This occurs when the test wrongly identifies a person as having the disease.
• D. False-negative: Person has disease and screening test result is negative (III). This occurs when the test wrongly identifies a person as disease-free.

Thus, the correct sequence is: (A) - (IV), (B) - (II), (C) - (I), (D) - (III).
