**Core Concept**
True negatives refer to the instances where a test or diagnostic tool correctly identifies individuals who do not have a particular disease or condition. This concept is crucial in understanding the accuracy and reliability of medical tests, especially in the context of screening and diagnosis.

**Why the Correct Answer is Right**
True negatives occur when a test yields a false-negative result, meaning it correctly identifies individuals without the disease. This is in contrast to false positives, where a test incorrectly identifies individuals with the disease. The test's sensitivity and specificity play a crucial role in determining the number of true negatives. A test with high specificity will have fewer false positives and, consequently, more true negatives.

**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect because a false positive result refers to a test that incorrectly identifies individuals with the disease, not those without it.

**Option B:**
This option is incorrect because a false negative result refers to a test that incorrectly identifies individuals without the disease, not those with it.

**Option C:**
This option is incorrect because a true positive result refers to a test that correctly identifies individuals with the disease, not those without it.

**Clinical Pearl / High-Yield Fact**
In medical testing, the number of true negatives is directly related to the test's specificity. A high-specificity test will have more true negatives, which is essential for accurate screening and diagnosis.

**Correct Answer: D.**
