Model Answer
(D) A person without the disease tests negative for the disease.
Explanation
A True Negative (TN) means the test correctly identifies a healthy person as healthy — no disease present, result is negative. This is the "correct rejection." Contrast with False Positive (healthy person tests positive) and False Negative (sick person tests negative).
