An observed score is reliable if it has a small error component and does not vary from observation to observation. Validity refers to the accuracy of the test in measuring what it is intended to measure, while reliability refers to the consistency of the test results over time and across different evaluators. The presence of a small true score component indicates that the test is measuring what it is intended to measure, but it does not affect the reliability of the test. Therefore, the best choice is D, reliable with a small error component.
